For the East generally regarded the magi as kings; and Damascus was anciently deemed to belong to Arabia, before it was transferred to Syrophœnicia on the division of the Syrias (by Rome). Its riches Christ then received, when He received the tokens thereof in the gold and spices; while the spoils of Samaria were the magi themselves. These having discovered Him and honored Him with their gifts, and on bended knee adored Him as their God and King, through the witness of the star which led their way and guided them, became the spoils of Samaria, that is to say, of idolatry, because, as it is easy enough to see, they believed in Christ.
