Act Acts, chapter Acts of the Apostles, chapter 18
And they came to Ephesus, and he left them there: but he himself entered into the synagogue, and reasoned with the Jews. And when they asked him to abide a longer time, he consented not; but taking his leave of them, and saying, I will return again unto you if God will, he set sail from Ephesus.Jas 4:15; 1Co 4:19
