Acts 18:18-23

18Paul 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].

19Then they arrived in Ephesus, and he left the others there; but he entered the synagogue and reasoned and debated with the Jews.

20When they asked him to stay for a longer time, he refused;

21but after telling them goodbye and saying, “I will return again if God is willing,” he set sail from Ephesus.

22When he had landed at Caesarea, he went up and greeted the church [at Jerusalem], and then went down to Antioch.

23After spending some time there, he left and traveled through the territory of Galatia and Phrygia, strengthening and encouraging all the disciples.
