Jonah 3:1-5 New Revised Standard Version (NRSV)
Conversion of Nineveh
3 The word of the Lord came to Jonah a second time, saying, 2 “Get up, go to Nineveh, that great city, and proclaim to it the message that I tell you.” 3 So Jonah set out and went to Nineveh, according to the word of the Lord. Now Nineveh was an exceedingly large city, a three days’ walk across. 4 Jonah began to go into the city, going a day’s walk. And he cried out, “Forty days more, and Nineveh shall be overthrown!” 5 And the people of Nineveh believed God; they proclaimed a fast, and everyone, great and small, put on sackcloth.
