Augustine of Hippo — as excerpted in the Catena Aurea on John 18:19-21

“(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.”
