Jonah 3:3-6

So Jonah arose, and went unto Nineveh, according to the word of Jehovah. Now Nineveh was an exceeding great city, of three days’ journey. And Jonah began to enter into the city a day’s journey, and he cried, and said, Yet forty days, and Nineveh shall be overthrown. And the people of Nineveh believed God; and they proclaimed a fast, and put on sackcloth, from the greatest of them even to the least of them. And the tidings reached the king of Nineveh, and he arose from his throne, and laid his robe from him, and covered him with sackcloth, and sat in ashes.
