19He came to Ephesus, and he left them there; but he himself entered into the synagogue, and reasoned with the Jews. 20When they asked him to stay a longer time, he declined; 21but taking his leave of them, and saying, "I must by all means keep this coming feast in Jerusalem, but I will return again to you if God wills," he set sail from Ephesus.
