Acts 22:26

When the centurion heard that ,.... The question put by Paul, which strongly suggested that he was a Roman:

he went and told the chief captain; what Paul had said: saying, take heed what thou dost ; or "art about to do"; lest some bad consequences should follow; lest he should affront the Roman people and senate, and lose his place, if not incur some corporeal punishment:

for this man is a Roman ; and it can never be answered to bind and beat a Roman.
