Matthew 14:7

So that he promised with an oath to give her whatsoever she would ask.

AD 1849
He promised. Wicked promises and wicked oaths are not binding. That promise is wicked, in which the thing promised is wicked, and that oath is not binding, by which impiety is promoted. (St. Isidore)

Hilary of Poitiers

AD 368
Shortly before, Herod indicated that he wanted to kill John. He hesitated for fear of the people, because they considered him to be a prophet. But now, upon the request for John’s death, since Herod was bound formally by the ritual of an oath, how is it that he suddenly becomes sorry? His former willingness is incompatible with his present unwillingness, and the annoyance he now feels is contrary to what he felt before. Previously there was an orderly sequence to what transpired, but now the situation has gotten out of hand. Sensual pleasure springing up from infidelity has seized the glory of the law. But the people, aware of the good things in the law, wink at the pleasurable circumstances not without misgivings as to their own peril. They know it is inappropriate for them to turn away from the glory of the commandments. Yet four factors cause them to give in to sin: an oath, fear of the leaders, the allurements of pleasure and a bad example.

Jerome

AD 420

Even as Joseph is called the father of Jesus by Mary herself, Herod now is said to be exceedingly sad because his guests thought that he was.

John Chrysostom

AD 407
Her reproach is twofold; first, that she danced, then that she pleased him, and so pleased him, as to obtain even murder for her reward. Do you see how savage he was? How senseless? How foolish? In putting himself under the obligation of an oath, while to her he gives full power over her request. But when he saw the evil actually ensuing, he was sorry, it is said; and yet in the first instance he had put him in bonds. Wherefore then is he sorry? Such is the nature of virtue, even among the wicked admiration and praises are its due. But alas for her madness! When she too ought to admire, yea, to bow down to him, for trying to redress her wrong, she on the contrary even helps to arrange the plot, and lays a snare, and asks a diabolical favor. But he was afraid for the oath's sake, it is said, and them that sat at meat with him. And how did you not fear that which is more grievous? Surely if you were afraid to have witnesses of your perjury, much more ought thou to fear having so ma...
