1 Kings 21:25-29 - Ahab's Repentance
25 But there was none like Ahab, who sold himself to do that which was evil in the sight of Yahweh, whom Jezebel his wife stirred up. 26 He did very abominably in following idols, according to all that the Amorites did, whom Yahweh cast out before the children of Israel.
27 It happened, when Ahab heard those words, that he tore his clothes, and put sackcloth on his flesh, and fasted, and lay in sackcloth, and went softly. 28 The word of Yahweh came to Elijah the Tishbite, saying, 29 "See how Ahab humbles himself before me? Because he humbles himself before me, I will not bring the evil in his days; but in his son's days will I bring the evil on his house."
