Jonah 3:5-9

The people of Nineveh believed and trusted in God; and they proclaimed a fast and put on sackcloth [in penitent mourning], from the greatest even to the least of them. When word reached the king of Nineveh [of Jonah’s message from God], he rose from his throne, took off his robe, covered himself with sackcloth and sat in the dust [in repentance]. He issued a proclamation and it said, “In Nineveh, by the decree of the king and his nobles: No man, animal, herd, or flock is to taste anything. They are not to eat or drink water. But both man and animal must be covered with sackcloth; and every one is to call on God earnestly and forcefully that each may turn from his wicked way and from the violence that is in his hands. Who knows, God may turn [in compassion] and relent and withdraw His burning anger (judgment) so that we will not perish.” [Joel 2:13, 14]
