18:40 And Elijah said unto them, Take the prophets of Baal; let not {o} one of them escape. And they took them: and Elijah brought them down to the brook Kishon, and slew them there.
(o) He commanded them that as they were truly persuaded to confess the only God: so they should serve him with all their power, and destroy the idolaters his enemies.
18:40 Elijah said - He takes the opportunity, whilst the peoples hearts were warm with the fresh sense of this great miracle. The brook Kishon - That their blood might be poured into that river, and thence conveyed into the sea, and might not defile the holy land. Slew them - As these idolatrous priests were manifestly under a sentence of death, passed upon such by the sovereign Lord of life and death, so Elijah had authority to execute it, being a prophet, and an extraordinary minister of God's vengeance. The four hundred prophets of the groves, it seems, did not attend, and so escaped, which perhaps Ahab rejoiced in. But it proved, they were reserved to be the instruments of his destruction, by encouraging him to go up to Ramoth - Gilead.
18:21-40 Many of the people wavered in their judgment, and varied in their practice. Elijah called upon them to determine whether Jehovah or Baal was the self-existent, supreme God, the Creator, Governor, and Judge of the world, and to follow him alone. It is dangerous to halt between the service of God and the service of sin, the dominion of Christ and the dominion of our lusts. If Jesus be the only Saviour, let us cleave to him alone for every thing; if the Bible be the world of God, let us reverence and receive the whole of it, and submit our understanding to the Divine teaching it contains. Elijah proposed to bring the matter to a trial. Baal had all the outward advantages, but the event encourages all God's witnesses and advocates never to fear the face of man. The God that answers by fire, let him be God: the atonement was to be made by sacrifice, before the judgment could be removed in mercy. The God therefore that has power to pardon sin, and to signify it by consuming the sin-offering, must needs be the God that can relieve from the calamity. God never required his worshippers to honour him in the manner of the worshippers of Baal; but the service of the devil, though sometimes it pleases and pampers the body, yet, in other things, really is cruel to it, as in envy and drunkenness. God requires that we mortify our lusts and corruptions; but bodily penances and severities are no pleasure to him. Who has required these things at your hands? A few words uttered in assured faith, and with fervent affection for the glory of God, and love to the souls of men, or thirstings after the Lord's image and his favour, form the effectual, fervent prayer of the righteous man, which availeth much. Elijah sought not his own glory, but that of God, for the good of the people. The people are all agreed, convinced, and satisfied; Jehovah, he is the God. Some, we hope, had their hearts turned, but most of them were convinced only, not converted. Blessed are they that have not seen what these saw, yet have believed, and have been wrought upon by it, more than they that saw it.
