1 Kings 21:25-27

25(There was never anyone like Ahab, who sold himself to do evil in the eyes of the LORD, urged on by Jezebel his wife.

26He behaved in the vilest manner by going after idols, like the Amorites the LORD drove out before Israel.)

27When Ahab heard these words, he tore his clothes, put on sackcloth and fasted. He lay in sackcloth and went around meekly.
