Isaiah 48 Study Notes: Stubborn Israel Refined and Sent Out of Babylon

The LORD rebukes Israel for using His name insincerely and reminds them He foretold events so idols would get no credit. For His own name He restrains His anger, refines them through affliction, and sends His chosen ally against Babylon, then calls the exiles to leave joyfully, warning that the wicked have no peace.

General

According to 48:14-15, what task is given to the one the LORD has called and brought?

Answer: To carry out the LORD's will against Babylon

The LORD summons everyone to hear which idol foretold these things; none did. Then He says the ally He has chosen will accomplish His wishes against Babylon and move against the Chaldeans. God Himself has spoken, called him, brought him, and will make his mission succeed (48:14-15). In the surrounding chapters this points to Cyrus, whom the LORD named as His shepherd (44:28), the man from a far land called to do His will (46:11). Daniel records the night the Chaldean king was killed and the kingdom passed to Darius the Mede (Daniel 5:30-31).

  • Isaiah 48:14-15 (BSB)
    “Come together, all of you, and listen: Which of the idols has foretold these things? The LORD’s chosen ally will carry out His desire against Babylon, and His arm will be against the Chaldeans. I, even I, have spoken; yes, I have called him. I have brought him, and he will succeed in his mission.”
    The LORD says the ally He has chosen and called will act against Babylon and succeed.
  • Isaiah 44:28 (BSB)
    “who says of Cyrus, ‘My shepherd will fulfill all that I desire,’ who says of Jerusalem, ‘She will be rebuilt,’ and of the temple, ‘Let its foundation be laid.’””
    The LORD named Cyrus as His shepherd who will fulfill His desire.
  • Isaiah 46:11 (BSB)
    “I summon a bird of prey from the east, a man for My purpose from a far-off land. Truly I have spoken, and truly I will bring it to pass. I have planned it, and I will surely do it.”
    The LORD calls a man from a far country to carry out His purpose.
  • Daniel 5:30-31 (BSB)
    “That very night Belshazzar king of the Chaldeans was slain, and Darius the Mede received the kingdom at the age of sixty-two.”
    Daniel records that Babylon's king was slain and the kingdom passed to the Mede.

What task does 48:14-15 assign to the one the LORD has called and brought?

Answer: To carry out the LORD's will against Babylon

After challenging the idols to match His foreknowledge, the LORD announces that His chosen ally will accomplish His pleasure against Babylon and move against the Chaldeans; the LORD has spoken, called, brought him, and will prosper his way (48:14-15). In context this points to Cyrus (44:28; 46:11). The success of the campaign is ascribed entirely to God's calling and enabling, and Daniel 5:30-31 records the fall of the Chaldean king and the kingdom passing to Darius the Mede.

  • Isaiah 48:14-15 (BSB)
    “Come together, all of you, and listen: Which of the idols has foretold these things? The LORD’s chosen ally will carry out His desire against Babylon, and His arm will be against the Chaldeans. I, even I, have spoken; yes, I have called him. I have brought him, and he will succeed in his mission.”
    The LORD says the ally He has chosen and called will act against Babylon and succeed.
  • Isaiah 44:28 (BSB)
    “who says of Cyrus, ‘My shepherd will fulfill all that I desire,’ who says of Jerusalem, ‘She will be rebuilt,’ and of the temple, ‘Let its foundation be laid.’””
    The LORD named Cyrus as His shepherd who will fulfill His desire.
  • Isaiah 46:11 (BSB)
    “I summon a bird of prey from the east, a man for My purpose from a far-off land. Truly I have spoken, and truly I will bring it to pass. I have planned it, and I will surely do it.”
    The LORD calls a man from a far country to carry out His purpose.
  • Daniel 5:30-31 (BSB)
    “That very night Belshazzar king of the Chaldeans was slain, and Darius the Mede received the kingdom at the age of sixty-two.”
    Daniel records that Babylon's king was slain and the kingdom passed to the Mede.

General

According to 48:9-11, why does the LORD hold back His anger and not wipe out His rebellious people?

Answer: Because of His own name, praise and glory

After exposing His people's rebellion, the LORD says He will hold back His wrath and keep it in check, so that they are not destroyed. He does this for His name and His praise (48:9). He acts for His own sake, because He will not let His name be dishonored or give His glory to anyone else (48:11). Israel's survival did not depend on Israel's goodness. God said the same about forgiving sins for His own sake (43:25), and Ezekiel reports Him saying He acts not for Israel's sake but for His holy name (Ezekiel 36:22). Paul shows that God's saving plan in Christ results in praise for His glorious grace (Ephesians 1:5-6). Because God's mercy rests on His own glory, it stands firm.

  • Isaiah 48:9 (BSB)
    “For the sake of My name I will delay My wrath; for the sake of My praise I will restrain it, so that you will not be cut off.”
    The LORD holds back His anger so that His people are not wiped out, for the sake of His name and praise.
  • Isaiah 48:11 (BSB)
    “For My own sake, My very own sake, I will act; for how can I let Myself be defamed? I will not yield My glory to another.”
    The LORD acts for His own sake and refuses to give His glory to another.
  • Isaiah 43:25 (BSB)
    “I, yes I, am He who blots out your transgressions for My own sake and remembers your sins no more.”
    The LORD blots out His people's transgressions for His own sake.
  • Ezekiel 36:22 (BSB)
    “Therefore tell the house of Israel that this is what the Lord GOD says: It is not for your sake that I will act, O house of Israel, but for My holy name, which you profaned among the nations to which you went.”
    The LORD tells Israel He will act not for their sake but for His holy name.
  • Ephesians 1:5-6 (BSB)
    “He predestined us for adoption as His sons through Jesus Christ, according to the good pleasure of His will, to the praise of His glorious grace, which He has freely given us in the Beloved One.”
    Paul says God's saving purpose leads to the praise of His glorious grace.

Theological

What ground does 48:9-11 give for the LORD's restraint of His wrath against His people?

Answer: Because of His own name, praise and glory

The ground lies entirely in God Himself: He defers His anger for His name's sake and restrains it for His praise, so that His people are not cut off (48:9); He acts for His own sake, unwilling to be defamed or to yield His glory to another (48:11). Mercy to the undeserving is secured by God's commitment to His own glory, not by any merit in the recipients. The same ground appears in 43:25 and Ezekiel 36:22, and Paul traces the whole of redemption to praise for God's glorious grace (Ephesians 1:5-6). This is why such grace is unconditional and sure.

  • Isaiah 48:9 (BSB)
    “For the sake of My name I will delay My wrath; for the sake of My praise I will restrain it, so that you will not be cut off.”
    The LORD holds back His anger so that His people are not wiped out, for the sake of His name and praise.
  • Isaiah 48:11 (BSB)
    “For My own sake, My very own sake, I will act; for how can I let Myself be defamed? I will not yield My glory to another.”
    The LORD acts for His own sake and refuses to give His glory to another.
  • Isaiah 43:25 (BSB)
    “I, yes I, am He who blots out your transgressions for My own sake and remembers your sins no more.”
    The LORD blots out His people's transgressions for His own sake.
  • Ezekiel 36:22 (BSB)
    “Therefore tell the house of Israel that this is what the Lord GOD says: It is not for your sake that I will act, O house of Israel, but for My holy name, which you profaned among the nations to which you went.”
    The LORD tells Israel He will act not for their sake but for His holy name.
  • Ephesians 1:5-6 (BSB)
    “He predestined us for adoption as His sons through Jesus Christ, according to the good pleasure of His will, to the praise of His glorious grace, which He has freely given us in the Beloved One.”
    Paul says God's saving purpose leads to the praise of His glorious grace.

General

According to 48:3-5, why did the LORD announce events long before they happened?

Answer: So His people could not credit their idols with what happened

The LORD says He announced earlier events well in advance, then suddenly acted, and they happened (48:3). He did this because He knew how stubborn His people were, with necks as rigid as iron and foreheads like bronze (48:4). By announcing events ahead of time, He made sure they could not say their idol or carved image had caused them (48:5). Their stubbornness was old: at the golden calf God called Israel stiff-necked (Exodus 32:9), and Jeremiah says they hardened themselves and refused to hear (Jeremiah 17:23). Earlier in Isaiah the LORD challenged the idols to predict anything at all (41:21-23).

  • Isaiah 48:3-5 (BSB)
    “I foretold the former things long ago; they came out of My mouth and I proclaimed them. Suddenly I acted, and they came to pass. For I knew that you are stubborn; your neck is iron and your forehead is bronze. Therefore I declared it to you long ago; I announced it before it came to pass, so that you could not claim, ‘My idol has done this; my carved image and molten god has ordained it.’”
    The LORD explains why He announced events long before they happened, given how stubborn His people were.
  • Exodus 32:9 (BSB)
    “The LORD also said to Moses, “I have seen this people, and they are indeed a stiff-necked people.”
    At the golden calf, the LORD called Israel a stiff-necked people.
  • Isaiah 41:21-23 (BSB)
    ““Present your case,” says the LORD. “Submit your arguments,” says the King of Jacob. “Let them come and tell us what will happen. Tell the former things, so that we may reflect on them and know the outcome. Or announce to us what is coming. Tell us the things that are to come, so that we may know that you are gods. Yes, do something good or evil, that we may look on together in dismay.”
    The LORD challenges idols to foretell the future and prove they are gods.
  • Jeremiah 17:23 (BSB)
    “Yet they would not listen or incline their ear, but they stiffened their necks and would not listen or receive My discipline.”
    Jeremiah says the people stiffened their necks and refused to listen.

Theological

What purpose does 48:3-5 give for the LORD's announcing events long in advance?

Answer: So His people could not credit their idols with what happened

God's prediction and fulfillment of the former things (48:3) was aimed at His people's obstinacy, pictured as a neck of iron and a brow of bronze (48:4): by announcing events beforehand, He forestalled any claim that an idol or molten image had ordained them (48:5). Prophecy here serves as proof of the LORD's sole deity against idols that cannot foretell anything (41:21-23), given to a people long known as stiff-necked (Exodus 32:9; Jeremiah 17:23).

  • Isaiah 48:3-5 (BSB)
    “I foretold the former things long ago; they came out of My mouth and I proclaimed them. Suddenly I acted, and they came to pass. For I knew that you are stubborn; your neck is iron and your forehead is bronze. Therefore I declared it to you long ago; I announced it before it came to pass, so that you could not claim, ‘My idol has done this; my carved image and molten god has ordained it.’”
    The LORD explains why He announced events long before they happened, given how stubborn His people were.
  • Exodus 32:9 (BSB)
    “The LORD also said to Moses, “I have seen this people, and they are indeed a stiff-necked people.”
    At the golden calf, the LORD called Israel a stiff-necked people.
  • Isaiah 41:21-23 (BSB)
    ““Present your case,” says the LORD. “Submit your arguments,” says the King of Jacob. “Let them come and tell us what will happen. Tell the former things, so that we may reflect on them and know the outcome. Or announce to us what is coming. Tell us the things that are to come, so that we may know that you are gods. Yes, do something good or evil, that we may look on together in dismay.”
    The LORD challenges idols to foretell the future and prove they are gods.
  • Jeremiah 17:23 (BSB)
    “Yet they would not listen or incline their ear, but they stiffened their necks and would not listen or receive My discipline.”
    Jeremiah says the people stiffened their necks and refused to listen.

General

In 48:18-19, what does the LORD say His people would have had if they had heeded His commands?

Answer: Peace flowing as a river, and numberless offspring

The LORD presents Himself as Israel's Redeemer and teacher, who shows them what is good for them and leads them in the right way (48:17). Then He speaks with longing: had they listened to His commands, their peace would have flowed like a river, their righteousness rolled in like ocean waves, and their offspring would have numbered like grains of sand, never cut off from Him (48:18-19). God's commands were for their good. The same longing appears in Psalm 81:13-14 and Deuteronomy 5:29, and Jesus grieved over Jerusalem because she was unwilling to come to Him (Matthew 23:37).

  • Isaiah 48:17-19 (BSB)
    “Thus says the LORD your Redeemer, the Holy One of Israel: “I am the LORD your God, who teaches you for your benefit, who directs you in the way you should go. If only you had paid attention to My commandments, your peace would have been like a river, and your righteousness like waves of the sea. Your descendants would have been as countless as the sand, and your offspring as numerous as its grains; their name would never be cut off or eliminated from My presence.””
    The LORD, who teaches His people for their good, laments what they missed by not heeding His commands.
  • Psalm 81:13-14 (BSB)
    “If only My people would listen to Me, if Israel would follow My ways, how soon I would subdue their enemies and turn My hand against their foes!”
    The LORD longs for His people to listen and follow His ways so He could subdue their enemies.
  • Deuteronomy 5:29 (BSB)
    “If only they had such a heart to fear Me and keep all My commandments always, so that it might be well with them and with their children forever.”
    The LORD wishes His people had a heart to fear Him and keep His commands, so that it would go well with them.
  • Matthew 23:37 (BSB)
    “O Jerusalem, Jerusalem, who kills the prophets and stones those sent to her, how often I have longed to gather your children together, as a hen gathers her chicks under her wings, but you were unwilling!”
    Jesus grieves over Jerusalem, which was unwilling to be gathered to Him.

Theological

According to 48:18-19, what blessings did Israel forfeit by not heeding the LORD's commands?

Answer: Peace flowing as a river, and numberless offspring

The Redeemer who teaches His people for their good and directs their path (48:17) laments the blessings forfeited by disobedience: peace like a river, righteousness like the sea's waves, and offspring as innumerable as sand, their name never cut off (48:18-19). The lament expresses God's genuine delight in His people's good and their real responsibility for refusing it. Psalm 81:13-14 and Deuteronomy 5:29 voice the same divine longing, and Jesus laments Jerusalem's unwillingness (Matthew 23:37).

  • Isaiah 48:17-19 (BSB)
    “Thus says the LORD your Redeemer, the Holy One of Israel: “I am the LORD your God, who teaches you for your benefit, who directs you in the way you should go. If only you had paid attention to My commandments, your peace would have been like a river, and your righteousness like waves of the sea. Your descendants would have been as countless as the sand, and your offspring as numerous as its grains; their name would never be cut off or eliminated from My presence.””
    The LORD, who teaches His people for their good, laments what they missed by not heeding His commands.
  • Psalm 81:13-14 (BSB)
    “If only My people would listen to Me, if Israel would follow My ways, how soon I would subdue their enemies and turn My hand against their foes!”
    The LORD longs for His people to listen and follow His ways so He could subdue their enemies.
  • Deuteronomy 5:29 (BSB)
    “If only they had such a heart to fear Me and keep all My commandments always, so that it might be well with them and with their children forever.”
    The LORD wishes His people had a heart to fear Him and keep His commands, so that it would go well with them.

General

In 48:20, what message are the departing exiles to proclaim to the farthest places?

Answer: That the LORD has set His servant Jacob free

The exiles are commanded to leave Babylon and escape the Chaldeans, announcing with joyful shouts to the farthest places that the LORD has set His servant Jacob free by redeeming him. To redeem means to buy back or set free. Then the passage recalls how God cared for His people in the wilderness: they did not go thirsty, because He opened the rock and made water stream out (48:20-21). Jeremiah also told God's people to flee from Babylon (Jeremiah 50:8). The water from the rock looks back to the wilderness journey after the Exodus (Exodus 17:6; Psalm 78:15-16), so the return from Babylon is pictured as a new rescue by the same faithful God.

  • Isaiah 48:20-21 (BSB)
    “Leave Babylon! Flee from the Chaldeans! Declare it with a shout of joy, proclaim it, let it go out to the ends of the earth, saying, “The LORD has redeemed His servant Jacob!” They did not thirst when He led them through the deserts; He made water flow for them from the rock; He split the rock, and water gushed out.”
    The exiles are commanded to leave Babylon with joy, proclaiming the LORD's redemption and recalling His care in the wilderness.
  • Jeremiah 50:8 (BSB)
    “Flee from the midst of Babylon; depart from the land of the Chaldeans; be like the he-goats that lead the flock.”
    Jeremiah also commands God's people to flee from Babylon.
  • Exodus 17:6 (BSB)
    “Behold, I will stand there before you by the rock at Horeb. And when you strike the rock, water will come out of it for the people to drink.” So Moses did this in the sight of the elders of Israel.”
    At Horeb the LORD brought water out of the rock for Israel in the wilderness.
  • Psalm 78:15-16 (BSB)
    “He split the rocks in the wilderness and gave them drink as abundant as the seas. He brought streams from the stone and made water flow down like rivers.”
    The psalmist recalls how God split rocks in the wilderness and gave His people abundant water.

Theological

What announcement are the exiles to carry to the farthest places according to 48:20?

Answer: That the LORD has set His servant Jacob free

The command to depart Babylon is accompanied by a joyful proclamation to the whole world: the LORD has bought back and freed His servant Jacob (48:20). The provision of water from the split rock (48:21) recalls the wilderness after the Exodus (Exodus 17:6; Psalm 78:15-16), framing the return from Babylon as a new exodus carried out by the same Redeemer. Jeremiah 50:8 issues the same summons to flee Babylon.

  • Isaiah 48:20-21 (BSB)
    “Leave Babylon! Flee from the Chaldeans! Declare it with a shout of joy, proclaim it, let it go out to the ends of the earth, saying, “The LORD has redeemed His servant Jacob!” They did not thirst when He led them through the deserts; He made water flow for them from the rock; He split the rock, and water gushed out.”
    The exiles are commanded to leave Babylon with joy, proclaiming the LORD's redemption and recalling His care in the wilderness.
  • Jeremiah 50:8 (BSB)
    “Flee from the midst of Babylon; depart from the land of the Chaldeans; be like the he-goats that lead the flock.”
    Jeremiah also commands God's people to flee from Babylon.
  • Exodus 17:6 (BSB)
    “Behold, I will stand there before you by the rock at Horeb. And when you strike the rock, water will come out of it for the people to drink.” So Moses did this in the sight of the elders of Israel.”
    At Horeb the LORD brought water out of the rock for Israel in the wilderness.
  • Psalm 78:15-16 (BSB)
    “He split the rocks in the wilderness and gave them drink as abundant as the seas. He brought streams from the stone and made water flow down like rivers.”
    The psalmist recalls how God split rocks in the wilderness and gave His people abundant water.

General

In 48:1-2, what is wrong with the way the house of Jacob uses the LORD's name?

Answer: They claimed the LORD's name without truth or righteousness

The LORD speaks to the house of Jacob, descendants of Judah, who take oaths in His name, call on Israel's God, name themselves for Jerusalem, and claim to rely on Him. But they do it without truth or righteousness (48:1-2). Their religion is outward only. Jeremiah confronted people who sinned openly and then came to the temple feeling safe (Jeremiah 7:9-10). Jesus quoted Isaiah about people whose lips honor God while their hearts stay distant (Matthew 15:8), and Paul warned of those who claim to know God yet deny Him by how they live (Titus 1:16).

  • Isaiah 48:1-2 (BSB)
    ““Listen to this, O house of Jacob, you who are called by the name of Israel, who have descended from the line of Judah, who swear by the name of the LORD, who invoke the God of Israel—but not in truth or righteousness— who indeed call yourselves after the holy city and lean on the God of Israel; the LORD of Hosts is His name.”
    The LORD addresses the house of Jacob, who take His name and lean on Him in name only.
  • Jeremiah 7:9-10 (BSB)
    “Will you steal and murder, commit adultery and perjury, burn incense to Baal, and follow other gods that you have not known, and then come and stand before Me in this house, which bears My Name, and say, ‘We are delivered, so we can continue with all these abominations’?”
    Jeremiah rebuked people who lived in open sin and then stood in the temple claiming safety.
  • Matthew 15:8 (BSB)
    “‘These people honor Me with their lips, but their hearts are far from Me.”
    Jesus quotes Isaiah about people who honor God with their lips while their hearts are distant.
  • Titus 1:16 (BSB)
    “They profess to know God, but by their actions they deny Him. They are detestable, disobedient, and unfit for any good deed.”
    Paul describes people who profess to know God but deny Him by their actions.

Theological

What does 48:1-2 expose in the house of Jacob's profession of the LORD's name?

Answer: They claimed the LORD's name without truth or righteousness

The indictment is hypocrisy: the house of Jacob swears by the LORD's name, invokes Israel's God, identifies with Jerusalem, and professes to lean on Him, yet without truth and without righteousness (48:1-2). The covenant name is on their lips while their lives contradict it. Jeremiah 7:9-10 exposes the same presumption, Jesus applies Isaiah's charge of lip-service to His contemporaries (Matthew 15:8), and Titus 1:16 describes those who profess God while denying Him in deed.

  • Isaiah 48:1-2 (BSB)
    ““Listen to this, O house of Jacob, you who are called by the name of Israel, who have descended from the line of Judah, who swear by the name of the LORD, who invoke the God of Israel—but not in truth or righteousness— who indeed call yourselves after the holy city and lean on the God of Israel; the LORD of Hosts is His name.”
    The LORD addresses the house of Jacob, who take His name and lean on Him in name only.
  • Jeremiah 7:9-10 (BSB)
    “Will you steal and murder, commit adultery and perjury, burn incense to Baal, and follow other gods that you have not known, and then come and stand before Me in this house, which bears My Name, and say, ‘We are delivered, so we can continue with all these abominations’?”
    Jeremiah rebuked people who lived in open sin and then stood in the temple claiming safety.

General

True or False: Chapter 48 ends by promising that everyone leaving Babylon, whether wicked or righteous, will enjoy the same peace.

Answer: False

This is false. Right after the joyful call to leave Babylon, the chapter ends with a solemn warning from the LORD: the wicked have no peace (48:22). Being freed from Babylon is not the same as being right with God. The same sentence closes a later section of Isaiah (57:21). Paul says sinners have not known the path of peace (Romans 3:17), but those who are justified, declared right with God, through faith are at peace with God by means of Jesus Christ (Romans 5:1).

  • Isaiah 48:22 (BSB)
    ““There is no peace,” says the LORD, “for the wicked.””
    The chapter closes with the LORD's solemn word about the wicked.
  • Isaiah 57:21 (BSB)
    ““There is no peace,” says my God, “for the wicked.””
    The same saying closes a later section of Isaiah.
  • Romans 5:1 (BSB)
    “Therefore, since we have been justified through faith, we have peace with God through our Lord Jesus Christ,”
    Peace with God comes to those justified through faith in Christ.
  • Romans 3:17 (BSB)
    “and the way of peace they have not known.””
    Paul says sinners have not known the way of peace.

Theological

True or False: 48:22 extends the peace of the return from Babylon equally to the wicked and the righteous.

Answer: False

This is false. The chapter closes with the LORD's sober refrain that the wicked have no peace (48:22), a caution that physical deliverance from Babylon does not equal reconciliation with God. The same refrain closes 57:21. The path of peace is unknown to sinners (Romans 3:17), and peace with God is given only to those justified by faith in Christ (Romans 5:1).

  • Isaiah 48:22 (BSB)
    ““There is no peace,” says the LORD, “for the wicked.””
    The chapter closes with the LORD's solemn word about the wicked.
  • Isaiah 57:21 (BSB)
    ““There is no peace,” says my God, “for the wicked.””
    The same saying closes a later section of Isaiah.
  • Romans 5:1 (BSB)
    “Therefore, since we have been justified through faith, we have peace with God through our Lord Jesus Christ,”
    Peace with God comes to those justified through faith in Christ.

    “and the way of peace they have not known.””

In 48:6-8, the LORD reveals new things His people had never heard. What does He say He knew about them?

Answer: That they had been rebels and deceitful from birth

The LORD now announces fresh, previously concealed things created just now, so that His people cannot claim they knew them already (48:6-7). They had never listened or understood; their ears had long been closed. He knew how false they were, and they had been called rebels from birth (48:8). The problem was not a recent slip; the nation had rebelled from its very beginnings. Scripture says the same about each person's heart. David confessed that he was sinful from the moment he was conceived (Psalm 51:5), another psalm says the wicked wander off from the very start of life (Psalm 58:3), and Paul says that by nature all of us deserved God's anger (Ephesians 2:3). This is why God's rescue must come from Him, as the next verses show.

  • Isaiah 48:6-8 (BSB)
    “You have heard these things; look at them all. Will you not acknowledge them? From now on I will tell you of new things, hidden things unknown to you. They are created now, and not long ago; you have not heard of them before today. So you cannot claim, ‘I already knew them!’ You have never heard; you have never understood; for a long time your ears have not been open. For I knew how deceitful you are; you have been called a rebel from birth.”
    The LORD announces new, hidden things and explains why His people had never truly heard.
  • Psalm 51:5 (BSB)
    “Surely I was brought forth in iniquity; I was sinful when my mother conceived me.”
    David confesses that he was sinful from the time of his conception.
  • Psalm 58:3 (BSB)
    “The wicked are estranged from the womb; the liars go astray from birth.”
    The psalmist says the wicked go astray from birth.
  • Ephesians 2:3 (BSB)
    “All of us also lived among them at one time, fulfilling the cravings of our flesh and indulging its desires and thoughts. Like the rest, we were by nature children of wrath.”

What does the LORD say in 48:8 that He knew about His people?

Answer: That they had been rebels and deceitful from birth

In announcing new and hidden things His people could not claim to have anticipated (48:6-7), the LORD diagnoses their condition: their ears have long been closed, and He knew how deceitful they were, known as rebellious since birth (48:8). Spoken of the nation, the charge means its rebellion is not occasional but runs back to its beginnings. This fits what Scripture teaches elsewhere about original sin, the corruption present from the start of life: sinful from conception (Psalm 51:5), estranged from birth (Psalm 58:3), by nature under God's wrath (Ephesians 2:3). The following verses ground their preservation solely in God's regard for His own name.

  • Isaiah 48:6-8 (BSB)
    “You have heard these things; look at them all. Will you not acknowledge them? From now on I will tell you of new things, hidden things unknown to you. They are created now, and not long ago; you have not heard of them before today. So you cannot claim, ‘I already knew them!’ You have never heard; you have never understood; for a long time your ears have not been open. For I knew how deceitful you are; you have been called a rebel from birth.”
    The LORD announces new, hidden things and explains why His people had never truly heard.
  • Psalm 51:5 (BSB)
    “Surely I was brought forth in iniquity; I was sinful when my mother conceived me.”
    David confesses that he was sinful from the time of his conception.
  • Psalm 58:3 (BSB)
    “The wicked are estranged from the womb; the liars go astray from birth.”
    The psalmist says the wicked go astray from birth.
  • Ephesians 2:3 (BSB)
    “All of us also lived among them at one time, fulfilling the cravings of our flesh and indulging its desires and thoughts. Like the rest, we were by nature children of wrath.”
    Paul says all of us were by nature children of wrath.

True or False: In 48:10 the LORD describes His people's suffering as a refining furnace in which He has tested them.

Answer: True

This is true. The LORD says He has refined His people, though not the way silver is refined, and has tested them in a furnace of hardship (48:10). The hardship of exile was not random; it was God's way of purifying His people. Zechariah speaks of God refining a remnant like silver and testing it like gold (Zechariah 13:9), and Malachi pictures the Lord sitting as a refiner who purifies Levi's descendants (Malachi 3:3). Peter tells believers that their trials test their faith, which is worth more than gold refined by fire (1 Peter 1:6-7).

  • Isaiah 48:10 (BSB)
    “See, I have refined you, but not as silver; I have tested you in the furnace of affliction.”
    The LORD describes His purifying discipline of His people.
  • Zechariah 13:9 (BSB)
    “This third I will bring through the fire; I will refine them like silver and test them like gold. They will call on My name, and I will answer them. I will say, ‘They are My people,’ and they will say, ‘The LORD is our God.’””
    The LORD says He will refine a remnant like silver and test them like gold.
  • Malachi 3:3 (BSB)
    “And He will sit as a refiner and purifier of silver; He will purify the sons of Levi and refine them like gold and silver. Then they will present offerings to the LORD in righteousness.”
    The Lord will sit as a refiner and purify the sons of Levi.
  • 1 Peter 1:6-7 (BSB)
    “In this you greatly rejoice, though now for a little while you may have had to suffer grief in various trials so that the proven character of your faith—more precious than gold, which perishes even though refined by fire—may result in praise, glory, and honor at the revelation of Jesus Christ.”
    Peter says trials prove the genuineness of faith, more precious than gold refined by fire.

True or False: 48:10 presents the affliction of God's people as a refining furnace in which He has tested them.

Answer: True

This is true. The LORD has refined His people, though not as silver, and tested them in a furnace of suffering (48:10). The exile is sovereign, purposeful discipline, not abandonment. The refining image recurs in Zechariah 13:9 and Malachi 3:3, and Peter applies it to believers whose faith is proved genuine through trials (1 Peter 1:6-7). For God's people, affliction becomes a means of their sanctification, their growth in holiness.

  • Isaiah 48:10 (BSB)
    “See, I have refined you, but not as silver; I have tested you in the furnace of affliction.”
    The LORD describes His purifying discipline of His people.
  • Zechariah 13:9 (BSB)
    “This third I will bring through the fire; I will refine them like silver and test them like gold. They will call on My name, and I will answer them. I will say, ‘They are My people,’ and they will say, ‘The LORD is our God.’””
    The LORD says He will refine a remnant like silver and test them like gold.
  • Malachi 3:3 (BSB)
    “And He will sit as a refiner and purifier of silver; He will purify the sons of Levi and refine them like gold and silver. Then they will present offerings to the LORD in righteousness.”
    The Lord will sit as a refiner and purify the sons of Levi.
  • 1 Peter 1:6-7 (BSB)
    “In this you greatly rejoice, though now for a little while you may have had to suffer grief in various trials so that the proven character of your faith—more precious than gold, which perishes even though refined by fire—may result in praise, glory, and honor at the revelation of Jesus Christ.”
    Peter says trials prove the genuineness of faith, more precious than gold refined by fire.

In 48:12-13, how does the LORD identify Himself to the people He has called?

Answer: As the first and last, who made the earth and the sky

The LORD calls Jacob, whom He has called, to listen: He is the one who was there at the beginning and will be there at the end, first and last. His own hand laid the earth's foundation and stretched out the sky, and at His call they all rise to attention (48:12-13). Israel's God is not one god among many but the eternal Creator. He used the same title earlier (44:6). In Revelation the risen Jesus takes this very title for Himself (Revelation 1:17; 22:13), showing that He shares the eternal identity of the LORD.

  • Isaiah 48:12-13 (BSB)
    “Listen to Me, O Jacob, and Israel, whom I have called: I am He; I am the first, and I am the last. Surely My own hand founded the earth, and My right hand spread out the heavens; when I summon them, they stand up together.”
    The LORD calls Jacob to listen and identifies Himself as the eternal Creator whose word commands the heavens and earth.
  • Isaiah 44:6 (BSB)
    “Thus says the LORD, the King and Redeemer of Israel, the LORD of Hosts: “I am the first and I am the last, and there is no God but Me.”
    The LORD earlier called Himself the first and the last, besides whom there is no God.
  • Revelation 1:17 (BSB)
    “When I saw Him, I fell at His feet like a dead man. But He placed His right hand on me and said, “Do not be afraid. I am the First and the Last,”
    The risen Christ tells John not to fear and calls Himself the First and the Last.
  • Revelation 22:13 (BSB)
    “I am the Alpha and the Omega, the First and the Last, the Beginning and the End.””
    Jesus calls Himself the Alpha and the Omega, the First and the Last.

How does the LORD identify Himself in 48:12-13?

Answer: As the first and last, who made the earth and the sky

Addressing Jacob, His called people, the LORD declares Himself first and last, the eternal One whose hand laid the earth's foundation and stretched out the sky, which stand at His summons (48:12-13). The title, already used in 44:6 in a statement of His sole deity, is claimed by the risen Christ in Revelation 1:17 and 22:13. That Jesus takes this self-designation of the LORD expresses His full divine identity and eternity.

  • Isaiah 48:12-13 (BSB)
    “Listen to Me, O Jacob, and Israel, whom I have called: I am He; I am the first, and I am the last. Surely My own hand founded the earth, and My right hand spread out the heavens; when I summon them, they stand up together.”
    The LORD calls Jacob to listen and identifies Himself as the eternal Creator whose word commands the heavens and earth.
  • Isaiah 44:6 (BSB)
    “Thus says the LORD, the King and Redeemer of Israel, the LORD of Hosts: “I am the first and I am the last, and there is no God but Me.”
    The LORD earlier called Himself the first and the last, besides whom there is no God.
  • Revelation 1:17 (BSB)
    “When I saw Him, I fell at His feet like a dead man. But He placed His right hand on me and said, “Do not be afraid. I am the First and the Last,”
    The risen Christ tells John not to fear and calls Himself the First and the Last.
  • Revelation 22:13 (BSB)
    “I am the Alpha and the Omega, the First and the Last, the Beginning and the End.””
    Jesus calls Himself the Alpha and the Omega, the First and the Last.
