Charles Ellicott Commentary John 18:33

"Pilate therefore entered again into the Praetorium, and called Jesus, and said unto him, Art thou the King of the Jews?" — John 18:33 (ASV)

Then Pilate entered into the judgment hall again, and called Jesus.—Better, Pilate therefore entered into the Praetorium (or palace) again, and called Jesus. . This was practically a private investigation, for the Jews could not enter the palace (John 18:28). .

Art thou the King of the Jews?—Compare to the note on Matthew 27:11 and Luke 23:2-3. Pilate, of course, knew of the charge brought against Him when he gave permission for the Roman cohort to apprehend Him.
