Jonah 3:4-6

New Revised Standard Version Catholic Edition

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.

⁶ When the news reached the king of Nineveh, he rose from his throne, removed his robe, covered himself with sackcloth, and sat in ashes.
