Acts 18:17-20
English Standard Version
18After this, Paul stayed many days longer and then took leave of the brothers and set sail for Syria, and with him Priscilla and Aquila. At Cenchreae he had cut his hair, for he was under a vow.
19And they came to Ephesus, and he left them there, but he himself went into the synagogue and reasoned with the Jews.
20When they asked him to stay for a longer period, he declined.
