Jonah 3:2-5

“Get up and go to the great city of Nineveh, and deliver the message I have given you.” This time Jonah obeyed the LORD’s command and went to Nineveh, a city so large that it took three days to see it all. On the day Jonah entered the city, he shouted to the crowds: “Forty days from now Nineveh will be destroyed!” The people of Nineveh believed God’s message, and from the greatest to the least, they declared a fast and put on burlap to show their sorrow.
