1 Kings 17:1

The history of Elijah begins somewhat abruptly. Usually, when a prophet enters, we have some account of his parentage, are told whose son he was and of what tribe; but Elijah drops (so to speak) out of the clouds, as if, like Melchisedek, he were without father, without mother, and without descent, which made some of the Jews fancy that he was an angel sent from heaven; but the apostle has assured us that he was a man subject to like passions as we are (Jam 5:17), which perhaps intimates, not only that he was liable to the common infirmities of human nature, but that, by his natural temper, he was a man of strong passions, more hot and eager than most men, and therefore the more fit to deal with the daring sinners of the age he lived in: so wonderfully does God suit men to the work he designs them for. Rough spirits are called to rough services. The reformation needed such a man as Luther to break the ice. Observe, 1. The prophet's name: Elijahu - "My God Jehovah is he" (so it signifies), "is he who sends me and will own me and bear me out, is he to whom I would bring Israel back and who alone can effect that great work." 2.
