And this came to pass when the Word became flesh, and took and made divine Him that was of David's seed. Wherefore he calls him Son, saying, "I will be to him a father, and he shall be to me a son." And again, "And 1 will make him my firstborn." From this it is then clearly explained that the firstborn Son of God will be of the seed of David, so that the Son of David is one and the same as the Son of God, and the Son of God one and the same as the Son of David. And thus it was prophesied that the Firstborn of the whole creation, Himself the Son of God, was to become Son of man.
