Jonah 3:4-6

4Jonah began by going a day’s journey into the city, proclaiming, “Forty more days and Nineveh will be overthrown.”

5The Ninevites believed God. A fast was proclaimed, and all of them, from the greatest to the least, put on sackcloth. 6When Jonah’s warning reached the king of Nineveh, he rose from his throne, took off his royal robes, covered himself with sackcloth and sat down in the dust.
