Judgment hall

Gr. praitorion (John 18:28, 33; 19:9; Matt. 27:27), "common
hall." 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.

The trial of our Lord was carried on in a room or office of
the palace. The "whole band" spoken of by Mark were gathered
together in the palace court.
