Acts 22:25-28
22:25 When they had stretched him out for the lash, Paul said to the centurion standing nearby, “Is it legal for you to lash a man who is a Roman citizen without a proper trial?”
22:26 When the centurion heard this, he went to the commanding officer and reported it, saying, “What are you about to do? For this man is a Roman citizen.”
22:27 So the commanding officer came and asked Paul, “Tell me, are you a Roman citizen?” He replied, “Yes.”
22:28 The commanding officer answered, “I acquired this citizenship with a large sum of money.” “But I was even born a citizen,” Paul replied.
