John Calvin on Acts 13:4

4. Being sent out by the Holy Ghost. There is no mention made here of the election made by the Church, because it was altogether a divine calling; the Church did only receive those who were offered them by the hand of God. He saith, that they came first to Seleucia, which was a city of Syria. There was, indeed, a country of the same name; but it is more likely that Luke speaketh of the city, which was not far from Cyprus by sea.
