Cosmas Indicopleustes : Let peoples serve thee, and let their princes bow down to thee, and be thou Lord over thy brethren, and let thy father's sons bow down to thee; cursed be every one that curseth thee, and blessed be every one that blesseth thee. But we see not all these things accomplished upon Jacob, but see rather that Jacob, having prostrated himself seven times upon the ground, made obeisance to Esau. And thirty kings, sprung from Esau, reigned before ever a king reigned in Israel; so that these blessings await Him who was expected to descend from them, namely, the Lord Christ, whom the whole scope of divine scripture has in view. — The Christian Topography, Book 5 Cyril of Alexandria : Afterward the power of blessing is transferred again to the Immanuel himself. "And let nations serve you, and princes bow down to you, and be lord of your brother." The Immanuel was called "the firstborn" when he became so with reference to us, "among many brothers." But for this reason we must not forget that he is God and the Lord of the universe. We worship him as God, and he has reigned as God over those who are called from the brothers through grace. "Who in the heavens shall be compared to the Lord, and who shall be likened to the Lord among the sons of God?" Therefore the Immanuel has reigned as God over those who were received into the brotherhood, and to him "every knee should bow in heaven and on earth, and under the earth, and every tongue should confess that Jesus Christ is Lord, to the glory of God the father." And cursed is he who curses, "and blessed is he that blesses." These words are quite clear. Those who curse are detestable and hateful to God; those who bless, that is, who announce his divine glory, are filled with heavenly and divine goods. This is the blessing of Jacob, whose strength refers to the Immanuel himself and to those who are justified in the faith. — GLAPHYRA ON GENESIS, 3.173B-C Hippolytus of Rome : And also the words "Let peoples serve you, and princes bow down to you" have been accomplished now. Whom else do the faithful peoples serve and the princes of the church worship but Christ, in whose name they also receive their salvation? The Word has predicted all this through Isaiah by saying, "My servants shall be called by a new name, which will be blessed on the earth; for they shall bless the true God, and those who swear upon the earth shall swear in the name of the true God." And he adds, "Behold, my servants shall eat, but you shall hunger; behold, my servants shall drink, but you shall thirst; behold, my servants shall exult with joy, but you shall be ashamed and shall cry for the vexation of your spirit."45Then he continues by saying, "Be lord of your brother, and the sons of your father shall bow to you." But nobody adored Jacob, nor did he become lord of his brother Esau; on the contrary, he ran away from him in a fright and was the first to adore him, for seven times. Therefore the words of Isaac have been accomplished in the Savior: He has become lord and master of those who are considered to be his brothers by the flesh, in order to be adored by them as their king. That is why Isaac says, "Cursed be everyone who curses you, and blessed be everyone who blesses you." — THE BLESSINGS OF THE PATRIARCHS 7
