Acts of the Apostles 22:25-27

When they tied Paul down to lash him, Paul said to the officer standing there, “Is it legal for you to whip a Roman citizen who hasn’t even been tried?” When the officer heard this, he went to the commander and asked, “What are you doing? This man is a Roman citizen!” So the commander went over and asked Paul, “Tell me, are you a Roman citizen?” “Yes, I certainly am,” Paul replied.
