Elijah gives precedence in everything to the Baal-priests, to take away all ground for cavil in case of failure. It is his object to make an impression on king and people; and he feels rightly that the impression will depend greatly on the contrast between their inability and the power given to him.

For ye are many - And therefore shall have the preference, and the advantage of being first in your application to the deity.

And Elijah said unto the prophets of Baal,.... Who agreed to this proposal, though not expressed; or they signified it by their silence. Ben Gersom thinks they agreed to it, because that, according to their belief, Baal was Mars, and in the sign of Aries, one of the fiery planets, and therefore fancied he could send down fire on their sacrifice; but Abarbinel is of opinion that it was the sun they worshipped, under the name of Baal, the great luminary which presides over the element of fire, and therefore had power to cause it to descend; and if not, they agreed to it, he thinks, for three reasons; one was necessity, they could not refuse, after the people had approved of it, lest they should rise upon them, and stone them; and another was, that Elijah proposed to offer without the temple, contrary to the law of his God, and therefore concluded he would not answer him by fire, and so they should be upon a par with him; and the third was, that they thought they should offer their bullocks together, so that, if fire descended, it would come upon them both, and then the dispute would be, whether his God, or their god, sent it; and so no proof could be made who was God, nor the matter in controversy decided:

choose you one bullock for yourselves, and dress it first; for ye are many; therefore in civility to them gave the choice of the bullock and the altar first, he being one and they many:

and call on the name of your gods, but put no fire under; under the wood on which was the sacrifice cut in pieces; and when they had so done, then they were to call on their gods to cause fire to descend upon it.

And Elijah said unto the prophets of Baal, Choose you one bullock for yourselves, and dress it first; for ye are many; and call on the name of your gods, but put no fire under.

18:25 Dress it first - And I am willing to give you the precedency. This he did, because if he had first offered, and God had answered by fire, Baal's priests would have desisted from making the trial on their part; and because the disappointment of the priests of Baal, of which he was well assured, would prepare the way for the people's attention to his words, and cause them to entertain his success with more affection; and this coming last would leave the greater impression upon their hearts. And this they accepted, because they might think, that if Baal answered them first, which they presumed he would, the people would be so confirmed and heightened in their opinion of Baal, that they might murder Elijah before he came to his experiment.

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.
