Jonah 3:2-5

“Arise, go to Nineveh, that great city, and call out against it the message that I tell you.” So Jonah arose and went to Nineveh, according to the word of the LORD. Now Nineveh was an exceedingly great city, three days’ journey in breadth. Jonah began to go into the city, going a day’s journey. And he called out, “Yet forty days, and Nineveh shall be overthrown!” And the people of Nineveh believed God. They called for a fast and put on sackcloth, from the greatest of them to the least of them.
