Forasmuch then as the children are partakers of flesh and blood, he also himself likewise took part of the same; that through death he might destroy him that had the power of death, that is, the devil; The children are partakers of flesh and blood - Since those children of God, who have fallen and are to be redeemed, are human beings; in order to be qualified to redeem them by suffering and dying in their stead, He himself likewise took part of the same - he became incarnate; and thus he who was God with God, became man with men. By the children here we are to understand, not only the disciples and all genuine Christians, as in Hebrews 2:13, but also the whole human race; all Jews and all Gentiles; so John 11:51, John 11:52 : He prophesied that Jesus should die for that nation; and not for that nation only, but also that he should gather together in one the Children of God that were scattered abroad; meaning, probably, all the Jews in every part of the earth. But collate this with 1 John 2:2, where: the evangelist explains the former words: He is the propitiation for our sins, (the Jews), and not for ours only, but for the sins of the Whole World. As the apostle was writing to the Hebrews only, he in general uses a Jewish phraseology, pointing out to them their own privileges; and rarely introduces the Gentiles, or what the Messiah has done for the other nations of the earth.
That through death - That by the merit of his own death, making atonement for sin, and procuring the almighty energy of the Holy Spirit, he might counterwork καταργηση, or render useless and ineffectual, all the operations of him who had the power, κρατος, or influence, to bring death into the world; so that death, which was intended by him who was a murderer from the beginning to be the final ruin of mankind, becomes the instrument of their exaltation and endless glory; and thus the death brought in by Satan is counterworked and rendered ineffectual by the death of Christ.
Him that had the power of death - This is spoken in conformity to an opinion prevalent among the Jews, that there was a certain fallen angel who was called מלאך המות malak hammaveth, the angel of death; i.e. one who had the power of separating the soul from the body, when God decreed that the person should die. There were two of these, according to some of the Jewish writers: one was the angel of death to the Gentiles; the other, to the Jews. Thus Tob haarets, fol. 31: "There are two angels which preside over death: one is over those who die out of the land of Israel, and his name is Sammael; the other is he who presides over those who die in the land of Israel, and this is Gabriel." Sammael is a common name for the devil among the Jews; and there is a tradition among them, delivered by the author of Pesikta rabbetha in Yalcut Simeoni, par. 2, f. 56, that the angel of death should be destroyed by the Messiah! "Satan said to the holy blessed God: Lord of the world, show me the Messiah. The Lord answered: Come and see him. And when he had seen him he was terrified, and his countenance fell, and he said: Most certainly this is the Messiah who shall cast me and all the nations into hell, as it is written Isaiah 25:8, The Lord shall swallow up death for ever." This is a very remarkable saying, and the apostle shows that it is true, for the Messiah came to destroy him who had the power of death. Dr. Owen has made some collections on this head from other Jewish writers which tend to illustrate this verse; they may he seen in his comment, vol. i., p. 456, 8vo. edition.
