Acts 18:23-28

23After spending some time there, he departed and went from one place to the next through the region of Galatia and Phrygia, strengthening all the disciples. 24Now a Jew named Apollos, a native of Alexandria, came to Ephesus. He was an eloquent man, competent in the Scriptures. 25He had been instructed in the way of the Lord. And being fervent in spirit, he spoke and taught accurately the things concerning Jesus, though he knew only the baptism of John. 26He began to speak boldly in the synagogue, but when Priscilla and Aquila heard him, they took him aside and explained to him the way of God more accurately. 27And when he wished to cross to Achaia, the brothers encouraged him and wrote to the disciples to welcome him. When he arrived, he greatly helped those who through grace had believed, 28for he powerfully refuted the Jews in public, showing by the Scriptures that the Christ was Jesus.
