The Greek word (praitorion) thus rendered in Mark 15:16 is rendered “common hall” (Matthew 27:27, marginal note, “governor's house”), “judgment hall,” (John 18:28, 33, marginal note, “Pilate's house”, 19:9; Acts 23:35), “palace” (Philippians 1:13). This is properly a military word. It denotes:

  1. the general's tent or headquarters
  2. the governor's residence, as in Acts 23:35 (Revised King James Version, “palace”)
  3. the praetorian guard (See PALACE), or the camp or quarters of the praetorian cohorts (Acts 28:16), the imperial guards in immediate attendance on the emperor, who was “praetor” or commander-in-chief.
