Acts 21:31-33

31While they were trying to kill him, the commander of the Roman regiment1 received a report that all Jerusalem was in turmoil. 32Immediately he took some soldiers and centurions and ran down to the crowd. When the people saw the commander and the soldiers, they stopped beating Paul.

33The commander came up and arrested Paul, ordering that he be bound with two chains. Then he asked who he was and what he had done.
