Acts 22:25-27
And as they bound him with thongs, Paul said unto the centurion that stood by, Is it lawful for you to scourge a man that is a Roman, and uncondemned?
When the centurion heard that, he went and told the chief captain, saying, Take heed what thou doest: for this man is a Roman.
Then the chief captain came, and said unto him, Tell me, art thou a Roman? He said, Yea.
