“Apollos” means given by Apollo
Apollos: a Jew from Alexandria, eloquent (which may also mean learned) and mighty in the Scriptures; one instructed in the way of the Lord, according to the imperfect view of the disciples of John the Baptist, (Acts 18:24) but on his coming to Ephesus during a temporary absence of St. Paul, A.D. 54, more perfectly taught by Aquila and Priscilla. After this he became a preacher of the gospel, first in Achaia and then in Corinth. (Acts 18:27; 19:1) When the apostle wrote his First Epistle to the Corinthians, Apollos was with or near him, (1 Corinthians 16:12) probably at Ephesus in A.D. 57. He is mentioned but once more in the New Testament, in (Titus 3:13) After this nothing is known of him. Tradition makes him bishop of Caesarea.
