Acts 18:18-26King James Version (KJV)
18 And Paul after this tarried there yet a good while, and then took his leave of the brethren, and sailed thence into Syria, and with him Priscilla and Aquila; having shorn his head in Cenchrea: for he had a vow.
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.
22 And when he had landed at Caesarea, and gone up, and saluted the church, he went down to Antioch.
23 And after he had spent some time there, he departed, and went over all the country of Galatia and Phrygia in order, strengthening all the disciples.
24 And a certain Jew named Apollos, born at Alexandria, an eloquent man, and mighty in the scriptures, came to Ephesus.
25 This man was instructed in the way of the Lord; and being fervent in the spirit, he spake and taught diligently the things of the Lord, knowing only the baptism of John.
26 And he began to speak boldly in the synagogue: whom when Aquila and Priscilla had heard, they took him unto them, and expounded unto him the way of God more perfectly.
