Acts 18:23-28
23And having spent some length of time there, he set out, and he walked in order through the region of Galatia and Phrygia, strengthening all the disciples. 24Now a certain Jew named Apollo, born at Alexandria, an eloquent man who was powerful with the Scriptures, arrived at Ephesus. 25He was learned in the Way of the Lord. And being fervent in spirit, he was speaking and teaching the things that are of Jesus, but knowing only the baptism of John. 26And so, he began to act faithfully in the synagogue. And when Priscilla and Aquila had heard him, they took him aside and expounded the Way of the Lord to him more thoroughly. 27Then, since he wanted to go to Achaia, the brothers wrote an exhortation to the disciples, so that they might accept him. And when he had arrived, he held many discussions with those who had believed. 28For he was vehemently and publicly reproving the Jews, by revealing through the Scriptures that Jesus is the Christ.
