Jonah 3:5-7

5The 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.

6When 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].

7He 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.
