Now Philip was from Bethsaida, of the city of Andrew and Peter.

 In the ancient world nearly everyone had two names. Greek was the universal language and nearly everyone had a name in his own native tongue, by which he was known to his friends. Thomas was the Aramaic and Didymus (Didumos - G1324) the Greek for a twin; Tabitha ( G5000; compare H6646) was the Aramaic and Dorcas (Dorkas - G1393) the Greek for a gazelle. Sometimes the Greek name was chosen because it sounded like the Aramaic name. A Jew who was called Eliakim or Abel in his own tongue might become Alcimus or Apelles to his Greek circle of acquaintances. So then Peter ( G4074) and Cephas ( G2786) are not different names; they are the same name in different languages.
