1 Kings 21:27-29

27And it came to pass when Ahab heard these words, that he rent his garments, and put sackcloth upon his flesh, and fasted, and lay in sackcloth, and went softly. 28And the word of Jehovah came to Elijah the Tishbite, saying, 29Seest thou how Ahab humbleth himself before me? because he humbleth himself before me, I will not bring the evil in his days: in his son's days will I bring the evil upon his house.
