Acts 18:24-28

A certain Jew named Apollos. Alexandria was the cultural center of the Greek-speaking Jews. The Septuagint [Greek translation of the Old Testament] was written there; and the most magnificent synagogue was there. Johnson thinks this man was a teacher of the Law. And taught correctly the facts about Jesus. He may have known as much of the facts as were contained in Mark's Gospel, in its mutilated form (without the longer ending), and so knew only John's water baptism. See note on Acts 19:4. He knew nothing of the final instructions Christ had given (Matthew 28:19-20) and the events of Pentecost. When Priscilla and Aquila heard him. The fact that he knew only the baptism of John distorted his understanding, and it was necessary to explain more correctly the Way of God. Nothing is said about him being re-immersed (baptized), but Acts 19:5 would strongly imply that he was. Apollos decided to go to Greece. The believers send letters along with him to "identify" him to their brothers (in Christ) there. He was a great help. His knowledge of the Old Testament Scriptures helped him present a powerful argument to prove Jesus is the Messiah.
