1 Kings 21:27-29

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

28Then the word of the Lord came to Elijah the Tishbite:

29“Have you noticed how Ahab has humbled himself before me? Because he has humbled himself, I will not bring this disaster in his day, but I will bring it on his house in the days of his son.”
