1 Kings 21:25-29 - Ahab's Repentance
25 For there was none at all like Ahab, that was so utterly given to work wickedness in the sight of the LORD, and that because Jezebel his wife pricked him forward. 26 And therefore he did exceeding abominably, in following Idols, in all things like as did the Amorites which the LORD cast out before the children of Israel.
27 When Ahab heard those words, he rent his clothes and put sackcloth about his flesh and fasted, and lay in sack and went comfortless. 28 And the word of the LORD came to Elijah the Tishbite, saying, 29 "Seest thou how Ahab humbleth himself before me? Because he so submitteth himself before me, I will not bring that evil in his days: but in his son's days, I will bring evil upon his house."
