Apostol § 41

In those days, when Paul had landed at Cæsaréa, and gone up and greeted the Church, he went down to Antioch. After he had spent some time there, he departed and went over all the region of Galátia and Phrýgia in order, strengthening all the disciples. Now a certain Jew named Apóllos, born at Alexandria, an eloquent man and mighty in the Scriptures, came to Éphesus. This man was instructed in the way of the Lord; and being fervent in spirit, he spoke and taught diligently the things of the Lord, though he knew only the baptism of John. And he began to speak boldly in the synagogue. When Áquila and Priscílla heard him, they took him unto them and expounded unto him the way of God more perfectly. And when he desired to pass into Acháia, the brethren wrote, exhorting the disciples to receive him; and when he arrived, he greatly helped those who had believed through grace; for he vigorously refuted the Jews publicly, showing by the Scriptures that the Christ was Jesus.
