1 Kings 21:27-29

When Ahab heard what Elijah had to say, he ripped his clothes to shreds, dressed in penitential rough burlap, and fasted. He even slept in coarse burlap pajamas. He tiptoed around, quiet as a mouse. Then GOD spoke to Elijah the Tishbite: “Do you see how penitently submissive Ahab has become to me? Because of his repentance I’ll not bring the doom during his lifetime; Ahab’s son, though, will get it.”
