John 19:3

When the Jews had cried out that they did not wish Jesus to be released on account of the passover, but Barabbas, Then Pilate therefore took Jesus, and scourged Him. Pilate seems to have done this for no reason but to satisfy the malice of the Jews with some punishment short of death. On which account he allowed his band to do what follows, or perhaps even commanded them. The Evangelist only says however that the soldiers did so, not that Pilate commanded them: 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 having called Him the King of the Jews, they put the royal dress upon Him, in mockery

For instead of a diadem, they put upon Him a crown of thorns, and a purple robe to represent the purple robe which kings wear. Matthew says, a scarlet robe, but scarlet and purple are different names for the same color. And though the soldiers did this in mockery, yet to us their acts have a meaning. For by the crown of thorns is signified the taking of our sins upon Him, the thorns which the earth of our body brings forth. And the purple robe signifies the flesh crucified. For our Lord is robed in purple, wherever He is glorified by the triumphs of holy martyrs.

It was not at the command of the governor that they did this, but in order to gratify the Jews. For neither were they commanded by him to go to the garden in the night, but the Jews gave them money to go. He bore however all these insults silently. Yet do you, when you hear of them keep stedfastly in your mind the King of the whole earth, and Lord of Angels bearing all these contumelies in silence, and imitate His example.

Thus were fulfilled what Christ had prophesied of Himself; thus were martyrs taught to suffer all that the malice of persecutors could inflict; thus that kingdom which was not of this world conquers the proud world, not by fierce fighting, but by patient suffering.

That the Jews might cease from their fury, seeing Him thus insulted, Pilate brought out Jesus before them crowned: Pilate therefore went forth again and says to them, Behold, I bring Him forth to you, that you may know that I find no fault in Him,.

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 says to them, Behold, the man as if to say, If you envy the King, spare the outcast ignominy overflows, let envy subside.

36. We have now reached the point at which we may study the Lord’s passion, strictly so called, as it is presented in the narrative of these four evangelists. Matthew commences his account as follows: “Then the soldiers of the governor took Jesus into the common hall, and gathered unto Him the whole band of soldiers. And they stripped Him, and put on Him a scarlet robe. And when they had platted a crown of thorns, they put it upon His head, and a reed in His right hand: and they bowed the knee before Him, and mocked Him, saying, Hail, King of the Jews!” At the same stage in the narrative, Mark delivers himself thus: “And the soldiers led Him away into the hall called Prætorium; and they called together the whole band. …
