Verse 8. - And I will give unto thee, and to thy seed after thee, the land wherein thou art a stranger, - literally, of thy sojournings (Genesis 12:9; Acts 7:5; Hebrews 11:9) - all the land of Canaan (vide Genesis 10:19), - for an everlasting possession. Literally, for a possession of eternity; i.e. the earthly Canaan should be retained by them so long as the arrangement then instituted should continue, provided always they complied with the conditions of the covenant; and the heavenly Canaan should be the inheritance of Abraham's spiritual children forever (vide Genesis 9:16; Genesis 13:15). And I will be their God. Literally, to them for Elohim (vide supra).

17:7-14 The covenant of grace is from everlasting in the counsels of it, and to everlasting in the consequences of it. The token of the covenant was circumcision. It is here said to be the covenant which Abraham and his seed must keep. Those who will have the Lord to be to them a God, must resolve to be to him a people. Not only Abraham and Isaac, and his posterity by Isaac, were to be circumcised, but also Ishmael and the bond-servants. It sealed not only the covenant of the land of Canaan to Isaac's posterity, but of heaven, through Christ, to the whole church of God. The outward sign is for the visible church; the inward seal of the Spirit is peculiar to those whom God knows to be believers, and he alone can know them. The religious observance of this institution was required, under a very severe penalty. It is dangerous to make light of Divine institutions, and to live in the neglect of them. The covenant in question was one that involved great blessings for the world in all future ages. Even the blessedness of Abraham himself, and all the rewards conferred upon him, were for Christ's sake. Abraham was justified, as we have seen, not by his own righteousness, but by faith in the promised Messiah.And I will give unto thee, and to thy seed after thee,.... To him in right, and to them in possession, and for an inheritance:

the land wherein thou art a stranger; or "the land of sojournings" or "pilgrimages" (l), which were many; for he often removed from place to place, and sometimes sojourned in one place, and sometimes in another:

all the land of Canaan, for an everlasting possession; this respects only the natural seed of Abraham, and those in the line of Isaac and Jacob, to whom this land was given to hold for ever, in case they were obedient to the will of God; and therefore whenever they were disobedient, they were carried captive from it, as they are at this day; but when they shall be converted, they will return to this land and possess it to the end of the world; and which was a figure of the heavenly inheritance, which is an eternal one, and will be enjoyed by all his spiritual seed to all eternity:

and I will be their God; as he was to all the natural seed of Abraham in a spiritual sense, to whom the adoption belonged, and whom he chose and separated as a peculiar people to himself, and bestowed in providence many peculiar favours upon them, both in a civil and religious way; and as he is to all his spiritual seed in an evangelic sense, to whom he stands in the relation of their covenant God and Father in Christ, in whom he blesses them with all spiritual blessings, and will continue to be so unto death, and to all eternity.
