Acts 21:31 In-Context

29 (For they had seen before with him in the city Trophimus an Ephesian, whom they supposed that Paul had brought into the temple.)
30 And all the city was moved, and the people ran together: and they took Paul, and drew him out of the temple: and forthwith the doors were shut.
31 And as they went about to kill him, tidings came unto the chief captain of the band, that all Jerusalem was in an uproar.
32 Who immediately took soldiers and centurions, and ran down unto them: and when they saw the chief captain and the soldiers, they left beating of Paul.
33 Then the chief captain came near, and took him, and commanded him to be bound with two chains; and demanded who he was, and what he had done.
