4 But Simeon also — he who had received an intimation from the Holy Ghost that he should not see death, until first he had beheld Christ Jesus— taking Him, the first-begotten of the Virgin, into his hands, blessed God, and said, “Lord, now let Your servant depart in peace, according to Your word: because my eyes have seen Your salvation, which You have prepared before the face of all people; a light to lighten the Gentiles, and the glory of Your people Israel;” confessing thus, that the infant whom he was holding in his hands, Jesus, born of Mary, was Christ Himself, the Son of God, the light of all, the glory of Israel itself, and the peace and refreshing of those who had fallen asleep.
For He was already despoiling men, by removing their ignorance, conferring upon them His own knowledge, and scattering abroad those who recognised Him, as Esaias says: “Call His name, Quickly spoil, Rapidly divide.” Now these are the works of Christ. He therefore was Himself Christ, whom Simeon carrying [in his arms] blessed the Most High; on beholding whom the shepherds glorified God; whom John, while yet in his mother's womb, and He (Christ) in that of Mary, recognising as the Lord, saluted with leaping; whom the Magi, when they had seen, adored, and offered their gifts [to Him], as I have already stated, and prostrated themselves to the eternal King, departed by another way, not now returning by the way of the Assyrians.
“For before the child shall have knowledge to cry, Father or mother, He shall receive the power of Damascus, and the spoils of Samaria, against the king of the Assyrians;” declaring, in a mysterious manner indeed, but emphatically, that the Lord did fight with a hidden hand against Amalek. For this cause, too, He suddenly removed those children belonging to the house of David, whose happy lot it was to have been born at that time, that He might send them on before into His kingdom; He, since He was Himself an infant, so arranging it that human infants should be martyrs, slain, according to the Scriptures, for the sake of Christ, who was born in Bethlehem of Judah, in the city of David.
