Verse 20. - So Ahab sent unto all the children of Israel, and gathered the prophets together unto Mount Carmel, ["The persecuting king became a passive instrument in the hand of the persecuted prophet" (Stanley). His ready compliance with Elijah's request, notwithstanding the bitter hatred of the man which he had just betrayed, is easily explained. It was not so much that "he bowed before the spiritual supremacy of the prophet, which impressed him" (Bahr), as that he hoped, from his reappearance, that he was now about to speak the word (1 Kings 17:1) and give rain upon the earth, and Ahab was willing to take any measures which would conduce with that result. It would take some days to collect the representatives of the tribes.]

18:17-20 One may guess how people stand affected to God, by observing how they stand affected to his people and ministers. It has been the lot of the best and most useful men, like Elijah, to be called and counted the troublers of the land. But those who cause God's judgments do the mischief, not he that foretells them, and warns the nation to repent.So Ahab sent unto all the children of Israel,.... By messengers, requiring their attendance at Mount Carmel at such a time, at least their chief and principal men:

and gathered the prophets together unto Mount Carmel; the four hundred and fifty prophets of Baal, but not the four hundred prophets of the groves; for of them we have no account afterwards, only of the former; it may be they were not at the command of Ahab, only of Jezebel, at whose table they ate, who would not suffer them to go.
