Acts 18:23-26

²³And 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.

²⁴And a certain Jew named Apollos, born at Alexandria, an eloquent man, and mighty in the scriptures, came to Ephesus.

²⁵This 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.

²⁶And 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.
