Here is, I. The covenant ratified (Gen 15:17); the sign which Abram desired was given, at length, when the sun had gone down, so that it was dark; for that was a dark dispensation.

1.The smoking furnace signified the affliction of his seed in Egypt. They were there in the iron furnace (Deu 4:20), the furnace of affliction (Isa 48:10), labouring in the very fire. They were there in the smoke, their eyes darkened, that they could not see to the end of their troubles, and themselves at a loss to conceive what God would do with them. Clouds and darkness were round about them.

2.The burning lamp denotes comfort in this affliction; and this God showed to Abram, at the same time that he showed him the smoking furnace. (1.) Light denotes deliverance out of the furnace; their salvation was as a lamp that burneth, Isa 62:1. When God came down to deliver them, he appeared in a bush that burned, and was not consumed, Exo 3:2. (2.) The lamp denotes direction in the smoke. God's word was their lamp: this word to Abram was so, it was a light shining in a dark place. Perhaps this burning lamp prefigured the pillar of cloud and fire, which led them out of Egypt, in which God was. (3.) The burning lamp denotes the destruction of their enemies who kept them so long in the furnace. See Zac 12:6. The same cloud that enlightened the Israelites troubled and burned the Egyptians.

3.The passing of these between the pieces was the confirming of the covenant God now made with him, that he might have strong consolation, being fully persuaded that what God promised he would certainly perform. It is probable that the furnace and lamp, which passed between the pieces, burnt and consumed them, and so completed the sacrifice, and testified God's acceptance of it, as of Gideon's (Jdg 6:21), Manoah's (Jdg 13:19, Jdg 13:20), and Solomon's, Ch2 7:1. So it intimates, (1.) That God's covenants with man are made by sacrifice (Psa 50:5), by Christ, the great sacrifice: no agreement without atonement. (2.) God's acceptance of our spiritual sacrifices is a token for good and an earnest of further favours. See Jdg 13:23. And by this we may know that he accepts our sacrifices if he kindle in our souls a holy fire of pious and devout affections in them.

II.The covenant repeated and explained: In that same day, that day never to be forgotten, the Lord made a covenant with Abram, that is, gave a promise to Abram, saying, Unto thy seed have I given this land, Gen 15:18. Here is,

1.A rehearsal of the grant. He had said before, To thy seed will I give this land, Gen 12:7; Gen 13:15. But here he says, I have given it; that is, (1.) I have given the promise of it, the charter is sealed and delivered, and cannot be disannulled. Note, God's promises are God's gifts, and are so to be accounted. (2.) The possession is as sure, in due time, as if it were now actually delivered to them. What God has promised is as sure as if it were already done; hence, it is said, He that believes hath everlasting life (Joh 3:36), for he shall as surely go to heaven as if he were there already.

2.A recital of the particulars granted, such as is usual in the grants of lands. He specifies the boundaries of the land intended hereby to be granted, Gen 15:18. And then, for the greater certainty, as is usual in such cases, he mentions in whose tenure and occupation these lands now were. Ten several nations, or tribes, are here spoken of (Gen 15:19-21) that must be cast our, to make room for the seed of Abram. They were not possessed of all these countries when God brought them into Canaan. The bounds are fixed much narrower, Num 34:2, Num 34:3, etc. But, (1.) In David's time, and Solomon's, their jurisdiction extended to the utmost of these limits, Ch2 9:26. (2.) It was their own fault that they were not sooner and longer in possession of all these territories. They forfeited their right by their sins, and by their own sloth and cowardice kept themselves out of possession. (3.) The land granted is here described in its utmost extent because it was to be a type of the heavenly inheritance, where there is room enough: in our father's house are many mansions. The present occupants are named, because their number, and strength, and long prescription, should be no hindrance to the accomplishment of this promise in its season, and to magnify God's love to Abram and his seed, in giving to that one nation the possessions of many nations, so precious were they in his sight, and so honourable, Isa 43:4.

The Kenites, etc. - Here are ten nations mentioned, though afterwards reckoned but seven; see Deu 7:1; Act 13:19. Probably some of them which existed in Abram's time had been blended with others before the time of Moses, so that seven only out of the ten then remained; see part of these noticed Genesis 10.

In this chapter there are three subjects which must be particularly interesting to the pious reader. 1. The condescension of God in revealing himself to mankind in a variety of ways, so as to render it absolutely evident that he had spoken, that he loved mankind, and that he had made every provision for their eternal welfare. So unequivocal were the discoveries which God made of himself, that on the minds of those to whom they were made not one doubt was left, relative either to the truth of the subject, or that it was God himself who made the discovery. The subject of the discovery also was such as sufficiently attested its truth to all future generations, for it concerned matters yet in futurity, so distinctly marked, so positively promised, and so highly interesting, as to make them objects of attention, memory, and desire, till they did come; and of gratitude, because of the permanent blessedness they communicated through all generations after the facts had taken place.

2.The way of salvation by faith in the promised Savior, which now began to be explicitly declared. God gives the promise of salvation, and by means in which it was impossible, humanly speaking, that it should take place; teaching us, 1. That the whole work was spiritual, supernatural, and Divine; and, 2. That no human power could suffice to produce it. This Abram believed while he was yet uncircumcised, and this faith was accounted to him for righteousness or justification; God thereby teaching that he would pardon, accept, and receive into favor all who should believe on the Lord Jesus Christ. And this very case has ever since been the standard of justification by faith; and the experience of millions of men, built on this foundation, has sufficiently attested the truth and solidity of the ground on which it was built.

3.The foundation of the doctrine itself is laid in the covenant made between God and Abram in behalf of all the families of the earth, and this covenant is ratified by a sacrifice. By this covenant man is bound to God, and God graciously binds himself to man. As this covenant referred to the incarnation of Christ; and Abram, both as to himself and posterity, was to partake of the benefits of it by faith; hence faith, not works, is the only condition on which God, through Christ, forgives sins, and brings to the promised spiritual inheritance. This covenant still stands open; all the successive generations of men are parties on the one side, and Jesus is at once the sacrifice and Mediator of it. As therefore the covenant still stands open, and Jesus is still the Lamb slain before the throne, every human soul must ratify the covenant for himself; and no man does so but he who, conscious of his guilt, accepts the sacrifice which God has provided for him. Reader, hast thou done so! And with a heart unto righteousness dost thou continue to believe on the Son of God? How merciful is God, who has found out such a way of salvation by providing a Savior every way suitable to miserable, fallen, sinful man! One who is holy, harmless, undefiled, and separate from sinners; and who, being higher than the heavens, raises up his faithful followers to the throne of his own eternal glory! Reader, give God the praise, and avail thyself of the sin-offering which lieth at the door.

And the Amorites,.... The same with the Amorite, Gen 10:16; they inhabited both on this and the other side Jordan:

and the Canaanites; which were a particular tribe or nation that bore the name of their great ancestor Canaan, see Gen 13:7,

and the Girgashites; the same with the Gergesenes in Mat 8:28; of these see Gen 10:16,

and the Jebusites; who inhabited Jerusalem and about it, which was first called Jebus, from the founder of this nation; see Gill on Gen 10:16.

Take me an heifer, &c.--On occasions of great importance, when two or more parties join in a compact, they either observe precisely the same rites as Abram did, or, where they do not, they invoke the lamp as their witness. According to these ideas, which have been from time immemorial engraven on the minds of Eastern people, the Lord Himself condescended to enter into covenant with Abram. The patriarch did not pass between the sacrifice and the reason was that in this transaction he was bound to nothing. He asked a sign, and God was pleased to give him a sign, by which, according to Eastern ideas, He bound Himself. In like manner God has entered into covenant with us; and in the glory of the only-begotten Son, who passed through between God and us, all who believe have, like Abram, a sign or pledge in the gift of the Spirit, whereby they may know that they shall inherit the heavenly Canaan.
