John 18:21

(Tr. cxiii. 3) For what they had heard and not understood, was not of such a kind, as that they could justly turn it against Him. And as often as they tried by questioning to find out some charge against Him, He so replied as to blunt all their stratagems, and refute their calumnies.

"Why askest thou Me? Ask them which heard Me." These are not the words of one speaking arrogantly, but of one confiding in the truth of what He had said. What therefore He said at the beginning, "If I bear witness of Myself, My witness is not true," this He now implieth, desiring to render His testimony abundantly credible. For when Annas mentioned the disciples, what saith He? "Dost thou ask Me concerning Mine? Ask Mine enemies, ask those who have plotted against Me, who have bound Me; let them speak." This is an unquestionable proof of truth, when one calls his enemies to be witnesses to what he saith.

Why askest thou Me? Ask them that have heard Me, what I spake unto them: behold, these know the things which I said. He rebukes those learned in the Law, for that they themselves sinned against the Law in which they took pride. For before He had been condemned, they passed premature sentence upon Him, and yet busied themselves in seeking for errors on His part. Why, then, He says, dost thou question Me, and call on Me to answer, Who have already endured your attack, and had punishment allotted Me before conviction? Or you may put another construction on what He said: Those who already hate Me, and receive with such extreme dishonour whatever I tell them of the things that are Mine, would not, perhaps, shrink from proclaiming what is false. Learn, then, from the lips of others. The search for witnesses would not be at all difficult, for these heard My words. Someone may, perhaps, imagine that He That knoweth the hearts and reins indicated some of the bystanders as having chanced to hear His words. But it is not so. For He referred to certain of the officers who once marvelled at His doctrine; and perhaps, to make our meaning clear, we ought to explain the time and occasion when this occurred. This same inspired Evangelist has told us, that once, when our Saviour Christ was preaching, and unfolding the doctrine concerning the Kingdom of Heaven to the assembled Jews, the teachers of the Jewish ordinances were sore enraged, and full of bitter envy of Him. and strove to remove Him from their midst. In the words of the Evangelist: And the chief priests and the Pharisees sent officers to take Him. But as our Saviour was continuing His long and full discourse, those which were sent by the Jews were convinced along with all the rest, and were more amazed than any one else among the multitude of His hearers. Thus speaks the Evangelist: The officers, therefore, came to the chief priests and Pharisees; and they said unto them, Why did ye not bring Him? The officers answered, Never man so spake. The Pharisees, therefore, answered them, Are ye also led astray? Observe how distressed at heart the Pharisees were, when they found that the officers had been at length convinced and sore amazed. The Saviour, then, knowing this, says: Ask them that have heard Me: behold, these know the things which I said. Either, then, He says, these know, looking at those who were then…
