SEV Biblia, Chapter 17:13 Debe ser circuncidado el nacido en tu casa, y el comprado por tu dinero; y estará mi pacto en vuestra carne para alianza perpetua.
Clarke's Bible Commentary - Genesis 17:13 Verse 13. He that is born in thy house] The son of a servant; he that is bought with thy money - a slave on his coming into the family.According to the Jewish writers the father was to circumcise his son; and the master, the servant born in his house, or the slave bought with money.If the father or master neglected to do this, then the magistrates were obliged to see it performed; if the neglect of this ordinance was unknown to the magistrates, then the person himself, when he came of age, was obliged to do it.
Matthew Henry Commentary Verses 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 wa 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, mus 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 churc 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 wa required, under a very severe penalty. It is dangerous to make light of Divine institutions, and to live in the neglect of them. The covenan 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 wa justified, as we have seen, not by his own righteousness, but by fait in the promised Messiah.
