Acts 18:19-28

19and he arrived at Ephesus, and left them there. But entering himself into the synagogue he reasoned with the Jews. 20And when they asked him that he would remain for a longer time [with them] he did not accede, 21but bade them farewell, saying, [I must by all means keep the coming feast at Jerusalem]; I will return to you again, if 1God will: and he sailed away from Ephesus. 22And landing at Caesarea, and having gone up and saluted the assembly, he went down to Antioch. 23And having stayed [there] some time, he went forth, passing in order through the country of Galatia and Phrygia, establishing all the disciples. 24But a certain Jew, Apollos by name, an Alexandrian by race, an eloquent man, who was mighty in the scriptures, arrived at Ephesus. 25He was instructed in the way of the Lord, and being fervent in his spirit, he spoke and taught exactly the things concerning Jesus, knowing only the baptism of John. 26And he began to speak boldly in the synagogue. And Aquila and Priscilla, having heard him, took him to [them] and unfolded to him the way of 2God more exactly. 27And when he purposed to go into Achaia, the brethren wrote to the disciples engaging them to receive him, who, being come, contributed much to those who believed through grace. 28For he with great force convinced the Jews publicly, shewing by the scriptures that Jesus was the Christ.
