6 But “when Herod,” says the Scripture, “had heard, he was troubled, and all Jerusalem with him.” Herod naturally, as being king, and afraid both for himself and for his children; but why Jerusalem? Surely the prophets had foretold Him a Saviour, and Benefactor, and a Deliverer from above. Wherefore then was Jerusalem troubled? From the same feeling which caused them before also to turn away from God when pouring His benefits on them, and to be mindful of the flesh-pots of Egypt, while in the enjoyment of great freedom.
But mark, I pray you, the accuracy of the prophets. For this selfsame thing also had the prophet foretold from the first, saying, “They would be glad, if they had been burnt with fire; for unto us a Child is born, unto us a Son is given.”
But nevertheless, although troubled, they seek not to see what has happened, neither do they follow the wise men, nor make any particular inquiry; to such a degree were they at once both contentious and careless above all men. For when they had reason rather to pride themselves that the king was born among them, and had attracted to Him the land of the Persians, and they were on the point of having all subject to them, as though their affairs had advanced towards improvement, and from the very outset His empire had become so glorious; nevertheless, they do not even for this become better. And yet they were but just delivered from their captivity there; and it was natural for them to think (even if they knew none of those things that are high and mysterious, but formed their judgment from what is present only), “If they thus tremble before our king at His birth, much more when grown up will they fear and obey Him, and our estate will be more glorious than that of the barbarians.”
