3 “Then Herod, when he had privily called the wise men, inquired of them diligently what time the star appeared:”
Attempting to slay that which was born—an act of extreme idiotcy not of madness only; since what had been said and done was enough to have withholden him from any such attempt. For those occurrences were not after the manner of man. A star, I mean, calling the wise men from on high; and barbarians making so long a pilgrimage, to worship Him that lay in swaddling clothes and a manger; and prophets too from of old, proclaiming beforehand all this—these and all the rest were more than human events: but nevertheless, none of these things restrained him. For such a thing is wickedness. It falls foul of itself, and is ever attempting impossibilities. And mark his utter folly. If on the one hand he believed the prophecy, and accounted it to be unchangeable, it was quite clear that he was attempting impossibilities; if again he disbelieved, and did not expect that those sayings would come to pass, he need not have been in fear and alarm, nor have formed any plot on that behalf. So that in either way his craft was superfluous.
And this too came of the utmost folly, to think that the wise men would make more account of him than of the Child that was born, for the sake of which they had come so long a journey. For if, before they saw, they were so inflamed with longing for Him; after they had seen with their eyes, and been confirmed by the prophecy, how hoped he to persuade them to betray the young Child to him?
Nevertheless, many as were the reasons to withhold him, he made the attempt; and having “privily called the wise men, he inquired of them.” Because he thought that Jews would be concerned in favor of the Child, and he never could expect that they would fall away unto such madness as to be willing to give up to His enemies their Protector and Saviour, and Him who had come for the deliverance of their nation. On account of this he both calls them privily, and seeks the time not of the Child, but of the star: thereby marking out the object of his chase so as to include far more than it. For the star, I think, must have appeared a long time before. It was a long time which the wise men had to spend on their journey. In order, therefore, that they might present themselves just after His birth (it being meet for Him to be worshipped in His very swaddling clothes, that the marvellous and strange nature of the thing might appear), the star, a long time before, makes itself visible. Whereas if at the moment of His birth in Palestine, and not before, it had been seen by them in the East, they, consuming a long time in their journey, would not have seen Him in swaddling clothes on their arrival. As to his slaying the children “from two years old and under,” let us not marvel; for his wrath and dread, for the sake of a fuller security, added very much to the time, so that not one might escape.
Having therefore called them, he says, “Go and search diligently for the young Child; and when you have found Him, bring me word again, that I may come and worship Him also.”
Do you see his extreme folly? Why, if you say these things in sincerity, wherefore do you inquire privily? But if intending to plot against Him, how is it you do not perceive, that from the fact of their being asked secretly the wise men will be able to perceive your craft? But as I have already said, a soul taken captive by any wickedness becomes more utterly senseless than any thing.
And he said not, “go and learn concerning the King,” but “concerning the young Child;” for he could not even endure to call Him by the name of His dominion.
