Jonah 3:4-6

Amplified Bible, Classic Edition

⁴ And Jonah began to enter into the city a day’s journey, and he cried, Yet forty days and Nineveh shall be overthrown!

⁵ So the people of Nineveh believed in God and proclaimed a fast and put on sackcloth [in penitent mourning], from the greatest of them even to the least of them.

⁶ For word came to the king of Nineveh [of all that had happened to Jonah, and his terrifying message from God], and he arose from his throne and he laid his robe aside, covered himself with sackcloth, and sat in ashes.
