Acts 22:24-29

the chief captain commanded him to be brought into the castle, bidding that he should be examined by scourging, that he might know for what cause they so shouted against him. And when they had tied him up with the thongs, Paul said unto the centurion that stood by, Is it lawful for you to scourge a man that is a Roman, and uncondemned? And when the centurion heard it, he went to the chief captain and told him, saying, What art thou about to do? for this man is a Roman. And the chief captain came and said unto him, Tell me, art thou a Roman? And he said, Yea. And the chief captain answered, With a great sum obtained I this citizenship. And Paul said, But I am a Roman born. They then that were about to examine him straightway departed from him: and the chief captain also was afraid when he knew that he was a Roman, and because he had bound him.
