27 But when Ahab heard this message, he tore his clothing, dressed in burlap, and fasted. He even slept in burlap and went about in deep mourning. 28 Then another message from the Lord came to Elijah: 29 "Do you see how Ahab has humbled himself before me? Because he has done this, I will not do what I promised during his lifetime. It will happen to his sons; I will destroy his dynasty."

Commentary on 1 Kings 21:17-29
(Read 1 Kings 21:17-29)
Blessed Paul complains that he was sold under sin, Romans 7:14, as a poor captive against his will; but Ahab was willing, he sold himself to sin; of choice, and as his own act and deed, he loved the dominion of sin. Jezebel his wife stirred him up to do wickedly. Ahab is reproved, and his sin set before his eyes, by Elijah. That man's condition is very miserable, who has made the word of God his enemy; and very desperate, who reckons the ministers of that word his enemies, because they tell him the truth. Ahab put on the garb and guise of a penitent, yet his heart was unhumbled and unchanged. Ahab's repentance was only what might be seen of men; it was outward only. Let this encourage all that truly repent, and unfeignedly believe the holy gospel, that if a pretending partial penitent shall go to his house reprieved, doubtless, a sincere believing penitent shall go to his house justified.
