Apollus

Apollus, an Alexandrian Jew, described in the Acts of the Apostles as an eloquent man, and mighty in the Scriptures, knowing only the baptism of John, who on coming to Ephesus (54 A.D.) was more perfectly taught by Aquila and Priscilla. He was a distinguished fellow-labourer of the apostle Paul; and in Corinth was especially successful as a Christian teacher, inasmuch that a party in the church called themselves by his name (1 Cor. iii. 4). By many he has been regarded as the author of the Epistle to the Hebrews.
