In all these passages the Revised Version renders “palace.” In Mark 15:16 the word is rendered “Praetorium” (q.v.), which is a Latin word, meaning literally the residence of the praetor, and then the governor's residence in general, though not a praetor. Throughout the Gospels the word “praitorion” has this meaning (compare Acts 23:35). Pilate's official residence when he was in Jerusalem was probably a part of the fortress of Antonia.
