For before the child shall have knowledge to cry, My father, and my mother, the riches of Damascus and the spoil of Samaria shall be taken away before the king of Assyria.
Read Chapter 8
Augustine of Hippo
For, before the child knew how to call his father and mother, as Isaiah had prophesied of him, he took the strength of Damascus and the spoils of Samaria. That is, before he uttered human speech through his humanity, he took the strength of Damascus or that which gave confidence to Damascus. For, in the estimation of the world, that city had flourished for some time on account of her riches. But preeminence in riches is gained by gold, and the magi as suppliants offered gold to Christ. - "Sermon 202.2"
And the words of Isaiah, “He shall take the power of Damascus and the spoils of Samaria,” meant that the power of the wicked demon that dwelt in Damascus should be crushed by Christ at his birth. This is shown to have taken place. For the magi, held in servitude (as spoils) for the commission of every wicked deed through the power of that demon, by coming and worshiping Christ, openly revolted against the power that had held them as spoils, which power the Scripture indicated by parable to be located in Damascus. And in the parables that sinful and wicked power is fittingly called Samaria. Now, even among you none can deny that Damascus was and is a part of the land of Arabia, although it now belongs to Syro-Phoenicia. So it would be to your advantage, my friends, to learn what you do not understand from us Christians, who have received the grace of God, and not to exert every effort to defend your peculiar teachings and scorn those of God. - "Dialogue with Trypho 78"
