1 Kings 21:27-29

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

28Then the word of the LORD 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 calamity during his days, but I will bring it upon his house in the days of his son.”
