Jon 3:2-5
"Set out for the great city of Nineveh, and announce to it the message that I will tell you." So Jonah made ready and went to Nineveh, according to the LORD'S bidding. Now Nineveh was an enormously large city; it took three days to go through it. Jonah began his journey through the city, and had gone but a single day's walk announcing, "Forty days more and Nineveh shall be destroyed," when the people of Nineveh believed God; they proclaimed a fast and all of them, great and small, put on sackcloth.
