And the hand of the LORD was on Elijah; and he girded up his loins, and ran before Ahab to the entrance of Jezreel. Ran before Ahab - Many think that Elijah ran before the king in order to do him honor; and much learned labor has been spent on this passage in order to show that Elijah had put himself at the head of a company of chanters who ran before the king reciting his praises, or the praises of God; a custom which still exists in Arabian countries! I believe all these entirely mistake the writer's meaning: Ahab yoked his chariot, and made all speed to Jezreel. The hand of the Lord, or, as the Targum says, the spirit of strength, came upon Elijah, and he girded up his loins, that is, tucked up his long garments in his girdle, and ran; and notwithstanding the advantage the king had by means of his chariot, the prophet reached Jezreel before him. There is no intimation here that he ran before the horses' heads. All this was intended to show that he was under the peculiar influence and inspiration of the Almighty, that the king might respect and fear him, and not do or permit to be done to him any kind of outrage.
