Acts 18:18-23

Paul, having remained many days longer, took leave of the brethren and put out to sea for Syria, and with him were Priscilla and Aquila. In Cenchrea he had his hair cut, for he was keeping a vow. They came to Ephesus, and he left them there. Now he himself entered the synagogue and reasoned with the Jews. When they asked him to stay for a longer time, he did not consent, but taking leave of them and saying, “I will return to you again if God wills,” he set sail from Ephesus. When he had landed at Caesarea, he went up and greeted the church, and went down to Antioch. And having spent some time there, he left and passed successively through the Galatian region and Phrygia, strengthening all the disciples.
