1 Kings 21:25-29

There certainly was no one like Ahab who sold himself to do evil in the sight of the LORD, because Jezebel his wife incited him. He acted very repulsively in following idols, in accordance with everything the Amorites had done, whom the LORD expelled [from the land] before the sons of Israel. Now when Ahab heard these words [of Elijah], he tore his clothes, put on sackcloth and fasted, and he lay in sackcloth and went about dejectedly (mourning). Then the word of the LORD came to Elijah the Tishbite, saying, “Do you see how Ahab has humbled himself before Me? Because he has humbled himself before Me, I will not bring the evil (catastrophe) in his lifetime, but in his son’s days I will bring evil upon his house.”
