Acts 18:24 (KJV)

And he came to Ephesus, and left them there: but he himself entered into the synagogue, and reasoned with the Jews.

When they desired him to tarry longer time with them, he consented not;

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.

And when he had landed at Caesarea, and gone up, and saluted the church, he went down to Antioch.

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.

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.

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.

And when he was disposed to pass into Achaia, the brethren wrote, exhorting the disciples to receive him: who, when he was come, helped them much which had believed through grace:

For he mightily convinced the Jews, and that publickly, shewing by the scriptures that Jesus was Christ.
