Acts 18:18-19
Acts 18:18-19 AMP
Paul stayed for a while longer, and then told the brothers and sisters goodbye and sailed for Syria; and he was accompanied by Priscilla and Aquila. At Cenchrea [the southeastern port of Corinth] he had his hair cut, because he was keeping a [Nazirite] vow [of abstention]. Then they arrived in Ephesus, and he left the others there; but he entered the synagogue and reasoned and debated with the Jews.
