I Kings 20:41

Then the disciple of the prophets drew the bandage quickly from his eyes, so that the king recognised him as a prophet, and announced to him the word of the Lord: "Because thou hast let go out of thy hand the man of my ban (i.e., Benhadad, who has fallen under my ban), thy life shall stand for his life, and thy people for his people," i.e., the destruction to which Benhadad was devoted will fall upon thee and thy people. The expression אישׁ־חרמי (man of my ban) showed Ahab clearly enough what ought to have been done with Benhadad. A person on whom the ban was pronounced was to be put to death (Lev 27:29).

This chapter is the history of a war between Ben-hadad king of Syria and Ahab king of Israel, in which Ahab was, once and again, victorious. We read nothing of Elijah or Elishain all this story; Jezebel's rage, it is probable, had abated, and the persecution of the prophets began to cool, which gleam of peace Elijah improved. He appeared not at court, but, being told how many thousands of good people there were in Israel more than he thought of, employed himself, as we may suppose, in founding religious houses, schools, or colleges of prophets, in several parts of the country, to be nurseries of religion, that they might help to reform the nation when the throne and court would not be reformed. While he was thus busied, God favoured the nation with the successes we here read of, which were the more remarkable because obtained against Ben-hadad king of Syria, whose successor, Hazael, was ordained to be a scourge to Israel. They must shortly suffer by the Syrians, and yet now triumphed over them, that, if possible, they might be led to repentance by the goodness of God. Here is, I. Ben-hadad's descent upon Israel, and his insolent demand (Kg1 20:1-11). II. The defeat Ahab gave him, encouraged and directed by a prophet (Kg1 20:12-21). III. The Syrians rallying again, and the second defeat Ahab gave them (Kg1 20:22-30). IV. The covenant of peace Ahab made with Ben-hadad, when he had him at his mercy (Kg1 20:31-34), for which he is reproved and threatened by a prophet (Kg1 20:35-43).
