Jonah 3:5-9 New Revised Standard Version (NRSV)
5 And the people of Nineveh believed God; they proclaimed a fast, and everyone, great and small, put on sackcloth.
6 When the news reached the king of Nineveh, he rose from his throne, removed his robe, covered himself with sackcloth, and sat in ashes. 7 Then he had a proclamation made in Nineveh: “By the decree of the king and his nobles: No human being or animal, no herd or flock, shall taste anything. They shall not feed, nor shall they drink water. 8 Human beings and animals shall be covered with sackcloth, and they shall cry mightily to God. All shall turn from their evil ways and from the violence that is in their hands. 9 Who knows? God may relent and change his mind; he may turn from his fierce anger, so that we do not perish.”
