That these things should thus take place as I have set them forth, the prophets had before predicted. In the writings of Solomon it is thus written: “The womb of a virgin was strengthened, and conceived: and a virgin was impregned, and became a mother in great pity.” In Isaiah it is thus written: “Behold, a virgin shall conceive, and bear a son, and ye shall call His name Immanuel;” which, being interpreted, is God with us. For He was with us on the earth, when He assumed flesh; and He was no less God in man, and man in God. That He was both God and man was declared before by the prophets. That He was God, Isaiah thus declares: “They shall fall down unto Thee, they shall make supplication unto Thee; since God is in Thee, and we knew it not, even the God of Israel. They shall be ashamed and confounded, all of them who oppose themselves to Thee, and shall go to confusion.” Also Jeremiah: “This is our God, and there shall none other be compared unto Him; He hath found out all the way of knowledge, and hath given it unto Jacob His servant, and to Israel His beloved. Afterward He was seen upon earth, and dwelt among men.” Likewise that He was man, the same Jeremiah says: “And He is man, and who knew Him?” Isaiah also thus speaks: “And the Lord shall send them a man who shall save them, and with judgment shall He heal them.” Also Moses himself in the book of Numbers: “There shall come a star out of Jacob, and a man shall arise out of Israel.” For this cause, therefore, being God, He took upon Him flesh, that, becoming a mediator between God and man, having overcome death, He might by His guidance lead man to God.
