General
In the song of 12:1, what has happened to God's anger toward the singer?
Answer: It has turned aside and given way to comfort
Chapter 12 is a song of praise for the day of salvation promised in chapter 11. The singer admits that God had been angry — rightly, because of sin — but now that anger has turned aside and God brings comfort (12:1). Salvation means God rescuing His people from sin and its results. God's anger at sin is real, yet for His people it gives way to mercy (Psalm 30:5; Isaiah 54:7-8). The New Testament shows how this happens: those made right with God by Christ's blood are rescued from God's wrath through Him (Romans 5:9).
- Isaiah 12:1 (BSB)“In that day you will say: “O LORD, I will praise You. Although You were angry with me, Your anger has turned away, and You have comforted me.”The singer praises God because His anger has given way to comfort.
- Psalm 30:5 (BSB)“For His anger is fleeting, but His favor lasts a lifetime. Weeping may stay the night, but joy comes in the morning.”The psalmist likewise sets God's brief anger against His lasting favor.
- Isaiah 54:7-8 (BSB)““For a brief moment I forsook you, but with great compassion I will bring you back. In a surge of anger I hid My face from you for a moment, but with everlasting kindness I will have compassion on you,” says the LORD your Redeemer.”God promises that a moment of anger gives way to everlasting compassion for His people.
- Romans 5:9 (BSB)“Therefore, since we have now been justified by His blood, how much more shall we be saved from wrath through Him!”Paul shows how wrath is turned away: those justified by Christ's blood are saved from it through Him.

According to 12:1, what has become of God's anger toward the one who sings?
Answer: It has turned aside and given way to comfort
The eschatological song confesses real divine anger that has now been turned away and replaced by comfort (12:1). Scripture consistently sets God's anger against His people as brief beside His lasting favor and compassion (Psalm 30:5; Isaiah 54:7-8). The ground of this turning is made explicit in the gospel: those justified by Christ's blood are rescued from wrath by Him (Romans 5:9) — His propitiation is why wrath gives way to comfort.
- Isaiah 12:1 (BSB)“In that day you will say: “O LORD, I will praise You. Although You were angry with me, Your anger has turned away, and You have comforted me.”The singer praises God because His anger has given way to comfort.
- Psalm 30:5 (BSB)“For His anger is fleeting, but His favor lasts a lifetime. Weeping may stay the night, but joy comes in the morning.”The psalmist likewise sets God's brief anger against His lasting favor.
- Isaiah 54:7-8 (BSB)““For a brief moment I forsook you, but with great compassion I will bring you back. In a surge of anger I hid My face from you for a moment, but with everlasting kindness I will have compassion on you,” says the LORD your Redeemer.”God promises that a moment of anger gives way to everlasting compassion for His people.
- Romans 5:9 (BSB)“Therefore, since we have now been justified by His blood, how much more shall we be saved from wrath through Him!”Paul shows how wrath is turned away: those justified by Christ's blood are saved from it through Him.

What does 12:4-6 call God's people to do with the LORD's name and deeds?
Answer: Spread news of them among nations everywhere
The second song in 12:4-6 turns outward: praise the LORD, make His name known, tell the peoples what He has done, and let the whole earth hear, because Israel's Holy One is great in Zion's midst. Zion here means Jerusalem, the city where God dwelt among His people. The psalms give the same call to tell the nations what God has done (Psalm 105:1), and Zephaniah calls the Daughter of Zion to sing because the LORD, the King of Israel, is in her midst (Zephaniah 3:14-15). In the New Testament God's people are chosen to make known the virtues of the One who called them into His light (1 Peter 2:9).
- Isaiah 12:4-6 (BSB)“and on that day you will say: “Give praise to the LORD; proclaim His name! Make His works known among the peoples; declare that His name is exalted. Sing to the LORD, for He has done glorious things. Let this be known in all the earth. Cry out and sing, O citizen of Zion, for great among you is the Holy One of Israel.””The second song calls God's people to praise Him before the nations because He is great among them.
- Psalm 105:1 (BSB)“Give thanks to the LORD, call upon His name; make known His deeds among the nations.”The psalm gives the same call to make God's deeds known among the nations.
- Zephaniah 3:14-15 (BSB)“Sing for joy, O Daughter of Zion; shout aloud, O Israel! Be glad and rejoice with all your heart, O Daughter of Jerusalem! The LORD has taken away your punishment; He has turned back your enemy. Israel’s King, the LORD, is among you; no longer will you fear any harm.”Zephaniah also calls Zion to sing because the LORD, Israel's King, is present among her.
- 1 Peter 2:9 (BSB)“But you are a chosen people, a royal priesthood, a holy nation, a people for God’s own possession, to proclaim the virtues of Him who called you out of darkness into His marvelous light.”Peter says God's people are chosen to make His virtues known, carrying the same outward calling.

What does the second song of 12:4-6 summon God's people to do with His name and works?
Answer: Spread news of them among nations everywhere
The hymn of 12:4-6 faces outward: praise and proclamation of the LORD's name and deeds among the peoples and through all the earth, grounded in the presence of Israel's Holy One in Zion's midst. The call to declare God's deeds to the nations is a psalm commonplace (Psalm 105:1); Zephaniah grounds Zion's song in the LORD's kingly presence (Zephaniah 3:14-15); and Peter describes the church as a chosen people who exist to make known God's virtues (1 Peter 2:9).
- Isaiah 12:4-6 (BSB)“and on that day you will say: “Give praise to the LORD; proclaim His name! Make His works known among the peoples; declare that His name is exalted. Sing to the LORD, for He has done glorious things. Let this be known in all the earth. Cry out and sing, O citizen of Zion, for great among you is the Holy One of Israel.””The second song calls God's people to praise Him before the nations because He is great among them.
- Psalm 105:1 (BSB)“Give thanks to the LORD, call upon His name; make known His deeds among the nations.”The psalm gives the same call to make God's deeds known among the nations.
- Zephaniah 3:14-15 (BSB)“Sing for joy, O Daughter of Zion; shout aloud, O Israel! Be glad and rejoice with all your heart, O Daughter of Jerusalem! The LORD has taken away your punishment; He has turned back your enemy. Israel’s King, the LORD, is among you; no longer will you fear any harm.”Zephaniah also calls Zion to sing because the LORD, Israel's King, is present among her.
- 1 Peter 2:9 (BSB)“But you are a chosen people, a royal priesthood, a holy nation, a people for God’s own possession, to proclaim the virtues of Him who called you out of darkness into His marvelous light.”Peter says God's people are chosen to make His virtues known, carrying the same outward calling.

What does 12:3 picture God's people doing with joy?
Answer: Drawing water from wells of salvation
In a dry land a spring was life itself. 12:3 pictures God's people gladly drawing water from springs of salvation — receiving God's rescue as freely and joyfully as cool water. Isaiah later invites everyone who is thirsty to come to the water and receive without paying (Isaiah 55:1). Jesus used the same kind of picture for Himself: the water He gives satisfies thirst forever and becomes a spring of eternal life (John 4:14), and He called the thirsty to come to Him and drink (John 7:37-38).
- Isaiah 12:3 (BSB)“With joy you will draw water from the springs of salvation,”Salvation is pictured as water drawn joyfully from springs.
- Isaiah 55:1 (BSB)““Come, all you who are thirsty, come to the waters; and you without money, come, buy, and eat! Come, buy wine and milk without money and without cost!”Isaiah later invites everyone who is thirsty to come and receive freely, without money.
- John 4:14 (BSB)“But whoever drinks the water I give him will never thirst. Indeed, the water I give him will become in him a fount of water springing up to eternal life.””Jesus describes the water He gives as a lasting spring of eternal life.
- John 7:37-38 (BSB)“On the last and greatest day of the feast, Jesus stood up and called out in a loud voice, “If anyone is thirsty, let him come to Me and drink. Whoever believes in Me, as the Scripture has said: ‘Streams of living water will flow from within him.’””Jesus invites the thirsty to come to Him and drink, using the same picture of saving water.

What joyful action does 12:3 use to picture receiving salvation?
Answer: Drawing water from wells of salvation
Salvation is imaged as water joyfully drawn from springs (12:3) — a gift received, not a wage earned. Isaiah's later free invitation to the thirsty (Isaiah 55:1) develops the same image, and Jesus presents Himself as the giver of the water that becomes a spring of eternal life (John 4:14) and calls the thirsty to come to Him and drink (John 7:37-38).
- Isaiah 12:3 (BSB)“With joy you will draw water from the springs of salvation,”Salvation is pictured as water drawn joyfully from springs.
- Isaiah 55:1 (BSB)““Come, all you who are thirsty, come to the waters; and you without money, come, buy, and eat! Come, buy wine and milk without money and without cost!”Isaiah later invites everyone who is thirsty to come and receive freely, without money.
- John 4:14 (BSB)“But whoever drinks the water I give him will never thirst. Indeed, the water I give him will become in him a fount of water springing up to eternal life.””Jesus describes the water He gives as a lasting spring of eternal life.

True or False: The confession in 12:2 echoes the song Israel sang after God brought them through the sea in Exodus 15.
Answer: True
This is true. The singer trusts and is not afraid, confessing God as his strength, his song and his salvation (12:2) — nearly the same words Moses and Israel sang after crossing the sea (Exodus 15:2), later repeated in Psalm 118:14. The future rescue is celebrated as a new exodus, which fits the highway out of exile pictured just before in 11:16.
- Isaiah 12:2 (BSB)“Surely God is my salvation; I will trust and not be afraid. For the LORD GOD is my strength and my song, and He also has become my salvation.””The singer trusts God without fear and confesses Him as strength, song and salvation.
- Exodus 15:2 (BSB)“The LORD is my strength and my song, and He has become my salvation. He is my God, and I will praise Him, my father’s God, and I will exalt Him.”Moses and Israel sang nearly the same confession after God brought them through the sea.
- Psalm 118:14 (BSB)“The LORD is my strength and my song, and He has become my salvation.”The psalmist repeats the same exodus confession, showing it became a standard song of deliverance.
