A Roman military official who served as the commander of a cohort (1,000 men). In New Testament usage it designated the commander of the Roman garrison (military post) in Jerusalem (for example, Acts 21:31; 22:24; 23:10; 24:22). Paul was placed under the tribune's protection after his arrest in Jerusalem (21:33).
