At the time of the offering of the evening sacrifice - i. e., probably "the ninth hour," or three o'clock. Thus there might still remain about five hours of light, during which the other events of the day were accomplished.

Lord God of Abraham, Isaac, and of Israel - This solemn address would carry back the thoughts of the pious to the burning bush of Horeb, and the words there spoken (marginal references), for there only had this mysterious formula been used before. Its use now was calculated to stir their faith and prepare them in some degree for God's answering "by fire."

That I have done all these things at thy word - i. e., "That I have been divinely directed in all that I have done publicly as a prophet, in proclaiming the drought, in gathering this assembly, and in proposing this trial; that I have not done them of my own mind" (marginal reference).

Lord God of Abraham - He thus addressed the Supreme Being, that they might know when the answer was given, that it was the same God whom the patriarchs and their fathers worshipped, and thus have their hearts turned back again to the true religion of their ancestors.

And it came to pass, at the time of the offering of the evening sacrifice,.... Which the people of God at Jerusalem were now attending to:

that Elijah the prophet came near; to the altar he had built, and on which he had laid the sacrifice:

and said; in prayer to God:

Lord God of Abraham, Isaac, and Jacob; the covenant God of the ancestors of his people, though they had now so fully departed from him:

let it be known this day that thou art God in Israel; and that there is no other:

and that I am thy servant; a true worshipper of him, and his faithful prophet and minister:

and that I have done all these things at thy word; restrained rain from the earth for some years past, and now had convened Israel, and the false prophets, together, that by a visible sign from heaven it might be known who was the true God; all which he did not of himself, but by the impulse, direction, and, commandment of the Lord.

After these preparations at the time of the evening sacrifice, Elijah drew near and prayed: "Lord God of Abraham, Isaac, and Israel (this name is used with deliberate purpose instead of Jacob: see at 1 Kings 18:31), let it be known this day that Thou art God in Israel, and I am Thy servant, and do all these things through Thy word. Hear me, Jehovah, hear me, that this people may know that Thou Jehovah art God, and turnest back their hearts!" (i.e., back from idols to Thyself.) This clearly expresses not only the object of the miracle which follows, but that of miracles universally. The perfects עשׂיתי and הסבּת are used to denote not only what has already occurred, but what will still take place and is as certain as if it had taken place already. עשׂיתי refers not merely to the predicted drought and to what Elijah has just been doing (Thenius), but to the miracle which was immediately about to be performed; and הסבּת to the conversion of the people to the Lord their God, for which Elijah's coming had already prepared the way, and which was still further advanced by the following miracle.

And it came to pass at the time of the offering of the evening sacrifice, that Elijah the prophet came near, and said, LORD God of Abraham, Isaac, and of Israel, let it be known this day that thou art God in Israel, and that I am thy servant, and that I have done all these things at thy word.

18:36 The evening sacrifice - This time he chose, that he might unite his prayers with the prayers of the godly Jews at Jerusalem, who at that time assembled together to pray. Lord God of, and c. - Hereby he shews faith in God's ancient covenant, and also reminds the people, of their relation both to God and to the patriarchs. Done these things - Brought this famine, gathered the people hither, and done what I have done, or am doing here; not in compliance with my own passions, but in obedience to thy command.

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.
