Act Acts, chapter Acts of the Apostles, chapter 18
He came to Ephesus, and he left them there; but he himself entered into the synagogue and reasoned with the Jews. When they asked him to stay with them a longer time, he declined; but taking his leave of them, he said, “I must by all means keep this coming feast in Jerusalem, but I will return again to you if God wills.” Then he set sail from Ephesus.Jas 4:15; 1Co 4:19
