Jonah 3:3-5

New Catholic Bible

³ Therefore, Jonah set out and journeyed to Nineveh in obedience to the command of the Lord.

Now Nineveh was an exceedingly large city; it required three days simply to walk across it. ⁴ Jonah began his journey into the city, walking for an entire day. Then he proclaimed, “After forty days, Nineveh will be overthrown.” ⁵ The people of Nineveh believed this message from God. They proclaimed a fast, and everyone, from the greatest to the least, put on sackcloth.
