Jonah 3:5 describes the moment the people of Nineveh took God’s warning seriously. They trusted the message of judgment the prophet Jonah had announced, and they showed that trust by fasting and putting on sackcloth, from the most important people down to the youngest and least. The verse is narration, told by the author of the book, rather than a speech from God or from Jonah.
The people of Nineveh believed God; and they proclaimed a fast, and put on sackcloth, from their greatest even to their least.

What Jonah 3:5 Means
The verse begins with “The people of Nineveh believed God.” The word “believed” here means more than holding a thought in mind. It means taking God at his word and acting on it. The people did not argue that the warning was exaggerated or wait to see whether it would come true. They accepted that the message came from God and that it required a response.
The two outward signs, a fast and sackcloth, were common ways in the ancient Near East to show grief, humility and repentance. Fasting meant going without food, and sackcloth was rough cloth worn against the skin. Both said, in visible form, “We are sorry, and we are not in control.” The phrase “from their greatest even to their least” tells us the response was not limited to one class of people. Everyone joined in.
The verse does not promise that repentance will always change God’s plans, and it does not give a formula for getting God to relent. It simply records what happened. The sincerity of the people is shown by what they did next, and the rest of the chapter continues the story.
The Context of Jonah 3:5
The book of Jonah is traditionally attributed to the prophet Jonah, son of Amittai, who is also mentioned in 2 Kings 14:25. Its audience was most likely the Israelites, and the story is told in a way that challenges their assumptions. Nineveh was the capital of the Assyrian Empire, a people feared and resented by Israel. Yet God sends his prophet to that enemy city, and the story shows the Assyrians responding with a seriousness that puts Jonah, the reluctant messenger, to shame.
Just before verse 5, God commissions Jonah a second time to preach to Nineveh, and Jonah goes, announcing only that the city will be overthrown in forty days. Just after the verse, the king of Nineveh joins the mourning, issues a decree for the whole city, and calls the people to turn from their violence. Read this way, verse 5 is the first sign of a city-wide turning, and it shows that the warning was received, not ignored.
Key Phrases in Jonah 3:5
Joel 2:13
Tear your heart, and not your garments, and turn to the LORD, your God; for he is gracious and merciful, slow to anger, and abundant in loving kindness, and relents from sending calamity.
(WEB)
Joel calls God’s people to rend their hearts and not merely their garments, which echoes the Ninevite sackcloth with a call to inner change. Read together, the two passages show that outward signs of repentance matter most when they express a turned heart.
Jonah 3:10
God saw their works, that they turned from their evil way. God relented of the disaster which he said he would do to them, and he didn’t do it.

This verse, the close of the same chapter, shows God responding to the people’s turning. It completes the story begun in verse 5 and helps you see that the Ninevites’ sincere repentance was met with God’s mercy.
A Short Prayer From Jonah 3:5
Lord, you speak to people who are far from you, and you speak to me as well. Help me to take your word seriously when it confronts me, and give me the courage to act on it without delay. Where I have been stubborn or proud, soften my heart. Where I have been comfortable with what is wrong, show me clearly what needs to change. Let my turning be sincere, and let my life show that I trust you more than my own excuses. Amen.
