Jonah 3:5-7

Amplified Bible, Classic Edition

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.

⁷ And he made proclamation and published through Nineveh, By the decree of the king and his nobles: Let neither man nor beast, herd nor flock, taste anything; let them not feed nor drink water.
