Acts 22:24-29

the commander ordered him to be brought into the barracks, stating that he should be examined by scourging so that he might find out the reason why they were shouting against him that way. But when they stretched him out with thongs, Paul said to the centurion who was standing by, “Is it lawful for you to scourge a man who is a Roman and uncondemned?” When the centurion heard this, he went to the commander and told him, saying, “What are you about to do? For this man is a Roman.” The commander came and said to him, “Tell me, are you a Roman?” And he said, “Yes.” The commander answered, “I acquired this citizenship with a large sum of money.” And Paul said, “But I was actually born a citizen.” Therefore those who were about to examine him immediately let go of him; and the commander also was afraid when he found out that he was a Roman, and because he had put him in chains.
