7. Unto thy seed will I give this land—God was dealing with Abram not in his private and personal capacity merely, but with a view to high and important interests in future ages. That land his posterity was for centuries to inhabit as a peculiar people; the seeds of divine knowledge were to be sown there for the benefit of all mankind; and considered in its geographical situation, it was chosen in divine wisdom as the fittest of all lands to serve as the cradle of a divine revelation designed for the whole world.

     9-21. 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.

     13-19. Abraham lifted up his eyes . . . and behold . . . a ram, &c.—No method was more admirably calculated to give the patriarch a distinct idea of the purpose of grace than this scenic representation: and hence our Lord's allusion to it (Joh 8:56).
