1 Kings 21:28

26He did very abominably in following idols, according to all that the Amorites did, whom the LORD cast out before the children of Israel.

27When Ahab heard those words, he tore his clothes, put sackcloth on his body, fasted, lay in sackcloth, and went about despondently.

28The LORD’s word came to Elijah the Tishbite, saying,

29“See how Ahab humbles himself before me? Because he humbles himself before me, I will not bring the evil in his days; but I will bring the evil on his house in his son’s day.”
