Acts 22:25-27

And as they bound him with thongs, Paul said to the centurion who stood by, “Is it lawful for you to scourge a man who is a Roman, and uncondemned?” When the centurion heard that, he went and told the commander, saying, “Take care what you do, for this man is a Roman.” Then the commander came and said to him, “Tell me, are you a Roman?” He said, “Yes.”
