Acts 18:18-23

And Paul, having tarried after this yet many days, took his leave of the brethren, and sailed thence for Syria, and with him Priscilla and Aquila: having shorn his head in Cenchreæ; for he had a vow. And they came to Ephesus, and he left them there: but he himself entered into the synagogue, and reasoned with the Jews. And when they asked him to abide a longer time, he consented not; but taking his leave of them, and saying, I will return again unto you if God will, he set sail from Ephesus. And when he had landed at Cæsarea, he went up and saluted the church, and went down to Antioch. And having spent some time there, he departed, and went through the region of Galatia, and Phrygia, in order, establishing all the disciples.
