The word of the Lord comes to Jonah a second time: arise, go to Nineveh, that great city, and proclaim to it the message he will tell him. This time Jonah obeys and goes to Nineveh. The city was so large that it took three days' journey to go through it. Jonah begins to enter it a day's journey and cries out that in forty days Nineveh will be overthrown.
The people of Nineveh believe God. They call a fast and put on sackcloth, from the greatest to the least. When the news reaches the king of Nineveh, he rises from his throne, takes off his robe, covers himself with sackcloth and sits in ashes. Then he has a decree proclaimed, with his nobles: let neither man nor beast, herd nor flock, taste anything or drink water; let everyone be covered with sackcloth and call out mightily to God, and let each turn from his evil way and from the violence that is in his hands.
The king wonders who knows whether God will turn and relent and turn from his fierce anger, so that they may not perish. God sees what they do, how they turn from their evil way, and God relents of the disaster he had said he would do to them, and he does not do it.
