And the word of the Lord came to Elijah the prophet,.... Where he now was, when this word came to him, is not certain; nor what he had been employed in for some time past, since we hear nothing of him since the unction of Elisha, other prophets of lesser note being employed in messages to Ahab from time to time; perhaps Elijah, while Ahab was engaged in war with the king of Syria, spent his time in founding or reviving the schools of the prophets, and instructing and training up those that were in them for public usefulness, since we afterwards hear of them; the word that came to him is, by the Targum, called the word of prophecy, as indeed it was, foretelling the destruction of Ahab and his house: saying; as follows.

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.

ELIJAH DENOUNCES JUDGMENTS AGAINST AHAB AND JEZEBEL. (1-Kings 21:17-29)
Hast thou killed, and also taken possession?--While Ahab was in the act of surveying his ill-gotten possession, Elijah, by divine commission, stood before him. The appearance of the prophet, at such a time, was ominous of evil, but his language was much more so (compare Ezekiel 45:8; Ezekiel 46:16-18). Instead of shrinking with horror from the atrocious crime, Ahab eagerly hastened to his newly acquired property.
