Acts of the Apostles 18:18-21

Paul stayed in Corinth for some time after that, then said good-bye to the brothers and sisters and went to nearby Cenchrea. There he shaved his head according to Jewish custom, marking the end of a vow. Then he set sail for Syria, taking Priscilla and Aquila with him. They stopped first at the port of Ephesus, where Paul left the others behind. While he was there, he went to the synagogue to reason with the Jews. They asked him to stay longer, but he declined. As he left, however, he said, “I will come back later, God willing.” Then he set sail from Ephesus.
