“But they cried out, Away with him, away with him, crucify him. Pilate saith unto them, Shall I crucify your King? The chief priests answered, We have no king but Cesar.”
John 19:15 — Greek Interlinear
Church Fathers on John 19:15
The Jews thought they could alarm Pilate more by the mention of Caesar, than by telling him of their law, as they had done above; We have a law, and by that law He ought to die, because He made Himself the Son of God. So it follows. But the Jews cried out, saying, you let this Man go, you are not Caesar’s friend; whosoever makes himself a king speaks against Caesar.

The tribunal is the seat of the judge, as the throne is the seat of the king, and the chair the seat of the doctor.
