Adam Clarke on Acts 13:14

They came to Antioch in Pisidia - This place is mentioned thus to distinguish it from Antioch in Syria, with which it had nothing in common but the name. There were several cities and towns in various districts of these countries called Antioch: some have reckoned up not less than twelve. Pisidia, in which this was situated, was a province of Asia Minor, near to Pamphylia, having Phrygia on the north, and Pamphylia on the south. The position of all these places may be seen on the map.

Into the synagogue on the Sabbath day - Though Paul was now on a special mission to the Gentiles, yet he availed himself of every opportunity, in every place, of making the first offer of salvation to the Jews.
