Augustine of Hippo
Catena Aurea · Johannesevangelium 19
Then Pilate therefore took Jesus, and scourged him. And the soldiers platted a crown of thorns, and put it on his head, and they put on him a purple robe, And said, Hail, King of the Jews! and they smote him with their hands. Pilate therefore went forth again, and saith unto them, Behold, I bring him forth to you, that ye may know that I find no fault in him. Then came Jesus forth, wearing the crown of thorns, and the purple robe. And Pilate saith unto them, Behold the man!
(Tr. cxvi) Hence it is apparent that these things were not done without Pilate’s knowledge, whether he commanded, or only permitted them, for the reason we have mentioned, viz. that His enemies seeing the insults heaped upon Him, might not thirst any longer for His blood: Then came Jesus forth, wearing the crown of thorns, and the purple robe: not the insignia of empire, but the marks of ridicule. And Pilate saith unto them, Behold the man! as if to say, If ye envy the King, spare the outcast. Ignominy overflows, let envy subside.
