1 Kings 21:27-29

27Now when Ahab heard those words, he tore his clothes, put sackcloth on his body, fasted, lay in sackcloth and walked about subdued.

28Then the word of Adonai came to Elijah the Tishbite saying:

29“Have you seen how Ahab has humbled himself before Me? Because he has humbled himself before Me, I will not bring the evil in his days, but in his son’s days I will bring the evil upon his house.”
