The Acts 18:24-28

Now a certain Jew, named Apollo, born at Alexandria, an eloquent man, came to Ephesus, one mighty in the scriptures. This man was instructed in the way of the Lord; and being fervent in spirit, spoke, and taught diligently the things that are of Jesus, knowing only the baptism of John. This man therefore began to speak boldly in the synagogue. Whom when Priscilla and Aquila had heard, they took him to them, and expounded to him the way of the Lord more diligently. And whereas he was desirous to go to Achaia, the brethren exhorting, wrote to the disciples to receive him. Who, when he was come, helped them much who had believed. For with much vigour he convinced the Jews openly, shewing by the scriptures, that Jesus is the Christ.
