1 Kings 21:26-30

He also acted very despicably in following idols, conforming to everything that the Amorites had done, whom the Lord drove out from the sons of Israel.

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 disaster in his days; I will bring the disaster upon his house in his son’s days.”
