Acts 22:24-29 - Paul Reveals His Roman Citizenship
24 the commanding officer ordered Paul to be brought back into the barracks. He told them to interrogate Paul by beating him with a lash so that he could find out the reason the crowd was shouting at Paul in this way. 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?"
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."
27 So the commanding officer came and asked Paul, "Tell me, are you a Roman citizen?" He replied, "Yes."
28 The commanding officer answered, "I acquired this citizenship with a large sum of money." "But I was even born a citizen," Paul replied.
29 Then those who were about to interrogate him stayed away from him, and the commanding officer was frightened when he realized that Paul was a Roman citizen and that he had had him tied up.
