Acts 22:28 - Matthew Poole's English Annotations on the Holy Bible

The historian relates, that the emperor Claudius sold this privilege to such foreigners as had not by any notable service merited to have it conferred upon them. At first it cost them very much to obtain it, as it did this chief captain; but afterwards it was more cheap and contemptible. I was free born; though Paul was born of Hebrew parents, yet he was born at Tarsus, to the natives of which town Augustus had given this privilege, for the assistance that the citizens afforded him in his wars with Brutus and Cassius; or, as some will have it, for favouring of Julius Caesar, this privilege was granted unto that place by him: and they, on the other side, to continue the sense of his favour, caused their town to be called Juliopolis, or the city of Julius.
