Is Titus Vespasian, who was involved with Bernice, the same as the Titus who traveled with Paul?
Then as now, just because a person has the same name, it doesn't mean they are the same person. There is only one Titus mentioned by name in the Bible and he was a preacher and traveling companion of Paul. Titus Flavius Vespasianus was the person his father and emperor, Vespasian, sent to put down the Jews. He is the one who destroyed Jerusalem and later became the next emperor of Rome. The Titus in the Bible and Titus Vespasianus are definitely two different people.
