Acts 18:19-21 King James Version (KJV)
19 And he came to Ephesus, and left them there: but he himself entered into the synagogue, and reasoned with the Jews.
20 When they desired him to tarry longer time with them, he consented not;
21 But bade them farewell, saying, I must by all means keep this feast that cometh in Jerusalem: but I will return again unto you, if God will. And he sailed from Ephesus.
