These are all referring to the same person. Tarsus is right over here in modern-day southern Turkey. And Paul, as I mentioned, he grows up in a conservative Jewish family, but he also has Roman citizenship. That's why he has this Roman name, Paul, and he has this Hebrew name, Saul. And he's educated in Jerusalem. And he doesn't enter into the story until we get to the fifth book of the New Testament, the Acts of the Apostles. And the Acts of the Apostles talks a lot about Peter, how he spreads the church, how he is persecuted, how he performs various miracles, but it also is where we get introduced to Paul.
