Acts 18:19-21

When they reached Ephesus, Paul left Priscilla and Aquila behind, then he went into the synagogue and spoke to the Jews. They asked him to stay longer, but he refused and said farewell to them, adding, “I will come back to you, if it is God’s will, after I go to Jerusalem to observe the feast.” Then he set sail from Ephesus for Caesarea.
