Jonah 3:2-5

“Go to the great city of Nineveh and proclaim to it the message I give you.” Jonah obeyed the word of the LORD and went to Nineveh. Now Nineveh was a very large city; it took three days to go through it. Jonah began by going a day’s journey into the city, proclaiming, “Forty more days and Nineveh will be overthrown.” The Ninevites believed God. A fast was proclaimed, and all of them, from the greatest to the least, put on sackcloth.
