Acts 8:5

Philip. This was not Philip, the apostle, for all the apostles remained at Jerusalem, but Philip, one of the seven (Ac 6:5).

The city of Samaria. The Greek does not render it certain that this was the capital named Samaria, as there is no definite article. It is literally "a city of Samaria". The district (see map) lies between Judea and Galilee. Samaria and Sychar were, at this time, two of its principal cities. It was probably one or the other of these to which Philip went.
