Theophylact of Ohrid
Catena Aurea · Lukasevangelium 23
And the whole multitude of them arose, and led him unto Pilate. And they began to accuse him, saying, We found this fellow perverting the nation, and forbidding to give tribute to Cæsar, saying that he himself is Christ a King. And Pilate asked him, saying, Art thou the King of the Jews? And he answered him and said, Thou sayest it. Then said Pilate to the chief priests and to the people, I find no fault in this man. And they were the more fierce, saying, He stirreth up the people, teaching throughout all Jewry, beginning from Galilee to this place.
It seems to me that he asked this question of Christ by way of deriding the wantonness or hypocrisy of the alleged charge. As if he said, Thou a poor humble naked man, with none to help Thee, art accused of seeking a kingdom, for which Thou wouldest need many to help Thee, and much money.
