Acts 22:23 (KJV)

And saw him saying unto me, Make haste, and get thee quickly out of Jerusalem: for they will not receive thy testimony concerning me.

And I said, Lord, they know that I imprisoned and beat in every synagogue them that believed on thee:

And when the blood of thy martyr Stephen was shed, I also was standing by, and consenting unto his death, and kept the raiment of them that slew him.

And he said unto me, Depart: for I will send thee far hence unto the Gentiles.

And they gave him audience unto this word, and then lifted up their voices, and said, Away with such a fellow from the earth: for it is not fit that he should live.

The chief captain commanded him to be brought into the castle, and bade that he should be examined by scourging; that he might know wherefore they cried so against him.

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.

And the chief captain answered, With a great sum obtained I this freedom. And Paul said, But I was free born.
