Short answer: Jonah was the one commanded to preach repentance in Nineveh. In Jonah 3:1–2, Yahweh's word came to him a second time, telling him to arise, go to the great city, and preach the message God would give him. What Jonah actually proclaimed was that Nineveh would be overthrown in forty days, and the people believed God, fasted, and turned from their evil ways. The passage's central claim is that God's word through a reluctant prophet produced a citywide turning, and God, seeing their turning, relented of the disaster he had announced.
A second commission to a reluctant prophet
Jonah 3:1–10 opens with a resumption, not a fresh start. The previous chapters have already told of a prophet of Israel who fled a commission toward Tarshish, was thrown into the sea, and prayed from inside the fish, ending with the confession that salvation belongs to Yahweh. The fish then releases him onto dry land, and the word of Yahweh comes to Jonah a second time. The setting is therefore a prophet already shown mercy, sent again to a foreign power. Nineveh is described as an exceedingly great city, three days' journey across, which measures both the size of the task and the reach of what follows.
The literary shape of the episode is a chain of speech and response. God commands, Jonah arises and goes, he cries out a single sentence about forty days and overthrow, and the city believes God. The response widens outward: the people fast and wear sackcloth, the news reaches the king, and he rises from his throne, removes his robe, sits in ashes, and issues a decree extending the mourning even to animals. The sermon is remarkably brief and gives no instructions, yet the narrative lingers on the response. The chapter closes with God seeing their works and relenting of the disaster he had announced.
The covenant setting presses the real question. Jonah is an Israelite prophet; Nineveh is a foreign power, and the mercy shown here reaches beyond Israel's borders. Yet the chapter is not a tidy success story. Chapter 4 immediately reports that Jonah was displeased and angry, and his prayer names God as gracious, merciful, slow to anger, and abundant in loving kindness, one who relents from harm. That frame keeps the reader honest. This is a unique prophetic mission displaying God's character, not a guarantee that any preaching campaign, nation, or person will certainly see revival or escape judgment.
The second commission and the words jonah carried
The chapter opens with a small phrase that carries a great deal: God's word came to Jonah "the second time." A messenger who had run from his commission is not discarded. The command itself is spare and direct, using two imperatives, arise and go, and then it qualifies the content of the preaching: Jonah is to speak the message God gives him. He is a bearer of another's words, not an author with freedom to soften or expand. The destination is named again, Nineveh, that great city, the same place he had fled toward the sea to avoid. Nothing about the assignment has been reduced.
What Jonah actually says is startlingly brief. He enters the city a day's journey and announces that in forty days Nineveh will be overthrown. There is no explicit call to repent in the recorded sermon, no explanation of God's character, no invitation. Yet the text says the people believed God, and they proclaimed a fast and put on sackcloth, from the greatest to the least. The king leaves his throne, removes his robe, and sits in ashes. His decree extends the mourning even to animals and names the change required: let them turn, everyone, from his evil way and from the violence in his hands.
The king's own words are cautious: who knows whether God will turn and relent. That is not presumption, and it is not a formula. The closing sentence is equally quiet. God saw their works, that they had turned from their evil way, and he relented of the disaster he had said he would do. The passage describes what God did in that place at that time. It does not guarantee that any preaching campaign, nation, or person will certainly see revival or escape judgment. What it does show plainly is a God who sends a failed messenger again, and who is free to show mercy.

The command to preach in nineveh and the God who relents
The one commanded to preach repentance in Nineveh was Jonah, a prophet of Israel, and the command came straight from Yahweh. Chapter 3 opens on the shoreline where the fish has just released him, so this is a resumption, not a fresh start. The word that came the second time repeats the first: arise, go to Nineveh, and preach the message I give you. The content is not Jonah's to compose. Nineveh is described as an exceedingly great city, three days' journey across, which measures both the size of the task and the reach of what follows.
What Jonah actually proclaimed was blunt: in forty days Nineveh would be overthrown. No call to repent appears in the announced message, yet the people believed God, proclaimed a fast, and put on sackcloth from the greatest to the least. The king leaves his throne, removes his robe, sits in ashes, and issues a decree extending the fast to animals. His hope is tentative, a question rather than a claim: who knows whether God will turn and relent? God saw their works, that they turned from their evil way, and he did not bring the disaster he had announced.
The frame around this scene keeps it honest. Jonah is an Israelite prophet sent to a foreign power, and the mercy shown to Nineveh presses the question of whether God's compassion stops at Israel's border. Chapter 4 answers the question about Jonah himself: he was exceedingly displeased and angry, and he said he knew God to be gracious, merciful, slow to anger, and abundant in loving kindness. This is a unique prophetic mission, not a formula promising that any campaign or nation will certainly see revival or escape judgment.
The chapter ends with God relenting, and chapter 4 immediately supplies Jonah's reaction, that he was angry and that he knew God to be gracious, merciful, slow to anger, and abundant in loving kindness. That final frame keeps the reader from treating the revival as a tidy success story.
Where readers differ over nineveh's turning and God's relenting
The text says the people of Nineveh believed God, fasted, and dressed in sackcloth, and that the king rose from his throne, removed his robe, and sat in ashes (3:5–6). What it does not say is what they understood about God. Some readers see a genuine turning, since God himself saw that they turned from their evil way (3:10). Others read a fear-driven civic reform, prompted by a prophet's warning and enforced by royal decree, and note that the account tells us nothing about their later life or worship. Both readings can point to the same verses. What the passage will not support is a claim that we know more about their hearts than the text discloses.
A second disagreement concerns how to speak of God relenting. Some stress that God genuinely responds to human turning, and the wording supports this: God saw their works, that they turned, and he relented of the disaster (3:10). Others stress that the announced judgment was conditional from the start, since the king himself asks who knows whether God will turn and relent (3:9). The text does not resolve the tension; it reports God's seeing and relenting without explaining how this fits with his unchanging purpose. Readers should be careful here. The passage invites worship, not a tidy system that explains away either God's mercy or his warning.
A third question is whether this episode sets a pattern for preaching to nations or stands as a singular prophetic sign. The commission was specific: arise, go to Nineveh, and preach the message I give you (3:2). The message was God's, not Jonah's, and the response was extraordinary. Some readers treat the account as a model for public leadership in repentance, since the king calls his people to turn from violence. Others see a unique event that proves God's freedom to show mercy where he chooses. What stays central across these readings is that God commissioned Jonah, the message was God's, the city turned, and God showed mercy. No campaign, nation, or person can claim this outcome in advance.
The passage ends with God's action, not Jonah's success: God saw, God relented, and he did not do it (3:10). That is where the comfort lies. Mercy belongs to God's freedom, and he extends it to a city that had no claim on him. Readers may differ over the details, but they can agree that the God who sent the prophet is the God who showed mercy, and that this mercy is grounds for humility rather than presumption.
The God who sends again, and the mercy that reaches outsiders
Jonah 3 opens with a second chance. The word of Yahweh comes to Jonah again, with the same charge: arise, go to Nineveh, and preach the message I give you (3:1–2). The prophet does not craft his own sermon; he carries a message entrusted to him. He arrives with one sentence, that in forty days Nineveh will be overthrown (3:4). What follows is startling: the people believe God, fast, and put on sackcloth, and even the king rises from his throne, strips off his robe, and sits in ashes (3:5–6). A pagan city responds where Israel's prophet had run.
The king's decree is careful and humble. He orders mourning for people and animals, and he calls everyone to turn from his evil way and from the violence in his hands (3:7–8). Then he says, who knows whether God will turn and relent (3:9). That is not a formula for guaranteed revival; it is the honest posture of a city that does not presume on mercy. God sees their works, that they turned, and he relents of the disaster he had announced (3:10). The text stresses God's response to genuine turning, not the mechanics of a successful campaign.
This prepares the way for Christ. A messenger is delivered through death-like confinement in the fish, then sent to speak to outsiders, and God shows mercy beyond Israel's borders. Jesus appealed to Jonah as a sign, pointing to a greater messenger delivered through death and raised to speak. Nineveh's welcome anticipates the mercy extended to all peoples in Christ. Yet chapter 4 keeps us honest: Jonah is angry that God is gracious (4:1–2). The same mercy that spared Nineveh exposes the prophet's heart, and ours, as needing that mercy too.
What faithful response looks like in ordinary life
Look closely at what Jonah is actually told to do. God says, "Arise, go to Nineveh, that great city, and preach to it the message that I give you." (Jonah 3:2). The task is to go and to speak what is given, not to design a message that guarantees an outcome. Jonah's sermon is one blunt sentence about forty days and overthrow, and the response comes from God's work, not the preacher's craft. That frees ordinary believers from measuring obedience by visible results. You are responsible for the going and the speaking, in your street, your workplace, your family. The fruit is not yours to manufacture or to grade.
Notice the phrase "the second time" (Jonah 3:1). After the flight, the prayer, and the fish, God's word comes again to the same failed servant with the same commission. Grace restores failed people to service rather than leaving them on the shelf. If you have fled some plain obedience, the honest response is not despair but return: go where you were sent, say what you were given to say. And notice how concrete the repentance in Nineveh is. The decree calls people to turn from their evil way and from the violence in their hands (Jonah 3:8). Examine actual conduct, not only religious feeling.
Chapter 4 keeps the story honest about our own hearts. When God relents and the city is spared, Jonah is furious, and he names God's mercy as the very reason he ran (Jonah 4:2). It is possible to preach grace and resent it when it lands on people we would rather judge. This passage shows God's mercy to one city through one prophet; it does not guarantee that any campaign, nation, or person will certainly see revival or escape judgment. What it does is call us to obey the commission, examine our conduct, and watch our hearts when God is generous to those we dislike.
Biblical fidelity check
We read this passage by following its plain, repetitive wording rather than filling gaps. The narrator gives no description of Nineveh's religion or the content of the people's faith, only that they believed God and turned from evil, so we should not claim more than the text says. The sermon itself is a bare announcement, with no explicit call to repent, yet the response is recorded as turning. The king's decree speaks of crying to God and forsaking violence. We also note that God's relenting is stated as fact without explanation, so we let the silence stand rather than resolving it.
The real disagreement is over what the Ninevites' belief amounted to and how to describe God's relenting. Some readers see genuine conversion; others see fear-driven reform, and the text does not describe their ongoing life. Some stress that God genuinely responds to human turning; others stress that the announced judgment was conditional from the start. Readers also differ over whether this is a pattern for preaching to nations or a singular sign. What stays central is that God commissioned Jonah, the message was God's, the city turned, and God showed mercy.

Frequently asked questions
Was Jonah the one commanded to preach in Nineveh, and what was he told to say?
Yes, Jonah was the one commanded, and the command came directly from Yahweh. Jonah 3:1–2 records that Yahweh's word came to Jonah the second time, after his flight and the fish, telling him to arise, go to Nineveh, and preach the message that God would give him. He was not told to compose his own sermon or negotiate terms; the content belonged to God. What Jonah actually cried out in the city was that in forty days Nineveh would be overthrown, a short and blunt announcement of coming judgment.
Did the people of Nineveh really repent, or were they only afraid?
The text describes more than panic; it describes a turning. Jonah 3:5 says the people believed God, proclaimed a fast, and put on sackcloth from the greatest to the least, and the king rose from his throne, removed his royal robe, and sat in ashes. His decree called on everyone to turn from his evil way and from the violence in his hands, and to cry mightily to God. Jonah 3:10 says God saw their works, that they turned from their evil way, which is the narrator's own summary of what happened. Fear may have started the response, but the passage records a change of conduct, not merely a change of mood.
Why did God relent after announcing that Nineveh would be overthrown?
God relented because he saw their turning from evil. Jonah 3:10 states that God saw their works, that they turned from their evil way, and he relented of the disaster he said he would do to them, and he did not do it. The announcement was a warning delivered through a prophet, and the king's own words in 3:9 had left the outcome open: who knows whether God will turn and relent. This is consistent with what Jonah himself later says about God's character in 4:2, that he is gracious, merciful, slow to anger, and abundant in loving kindness. The passage presents this as God's mercy toward a particular city at a particular moment, not a formula that guarantees any preaching campaign or nation will escape judgment.
