John Chrysostom
Having failed in this way to reject and destroy the event, they return again to the former matter. They examine the manner of the healing, like men searching everywhere for a beast lying in a safe place, running here and there. They return to the earlier words, but again so that, by repeated questions, they may display all their own worthlessness.
Do you see the boldness of the beggar before the scribes and Pharisees? So powerful is truth, and so powerless is falsehood. Truth, even when found in simple people, makes them glorious. Falsehood, even when on the side of the powerful, shows them weak.
The beggar's words mean this: you do not heed my words, so I will speak no more. I will not answer your frequent and empty questions. You ask not in order to learn, but to mock my words.
