The military tribune Claudius Lysias enters the New Testament narrative when he protects Paul of Tarsus from a hostile Jewish mob on the outside of the Temple grounds in Jerusalem (Acts 21.30-32). The Acts text does not explicitly state why the tribune arrests Paul aside from asking "who he was and what he had done" (Acts 21.33); consequently, it appears Paul is detained for investigation as reflected later in Paul's interrogation in the Antonian barracks because he was a cause of instigation among the Jews (Acts 22.23-24).
