Acts 18:18-21

¹⁸Paul, 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. ¹⁹They came to Ephesus, and he left them there. Now he himself entered the synagogue and reasoned with the Jews. ²⁰When they asked him to stay for a longer time, he did not consent, ²¹but taking leave of them and saying, “I will return to you again if God wills,” he set sail from Ephesus.
