A Jew “born at Alexandria,” a man well versed in the Scriptures and eloquent (Acts 18:24; R.V., “learned”). He came to Ephesus (about A.D. 49), where he spake “boldly” in the synagogue (18:26), although he did not know as yet that Jesus of Nazareth was the Messiah. Aquila and Priscilla instructed him more perfectly in “the way of God”, i.e., in the knowledge of Christ. He then proceeded to Corinth, where he met Paul (Acts 18:27; 19:1). He was there very useful in watering the good seed Paul had sown (1 Cor. 1:12), and in gaining many to Christ. His disciples were much attached to him (1 Cor. 3:4-7, 22). He was with Paul at Ephesus when he wrote the First Epistle to the Corinthians; and Paul makes kindly reference to him in his letter to Titus (3:13). Some have supposed, although without sufficient ground, that he was the author of the Epistle to the Hebrews.
Apollos
Apollos arrives in Ephesus as “an eloquent man, and mighty in the scriptures,” born in Alexandria (Acts 18:24). He teaches boldly in the synagogue, though he knows only John’s baptism. Aquila and Priscilla, a couple who had heard him, take him aside and explain the way of God more fully. Afterward he crosses to Achaia, where he helps believers and publicly shows from the Scriptures that Jesus is the Christ. At Corinth some say, “I am of Paul; and I of Apollos” (1 Corinthians 1:12). Acts 18:24-28 is the heart of his story.

Acts
And a certain Jew named Apollos, born at Alexandria, an eloquent man, and mighty in the scriptures, came to Ephesus.
This man was instructed in the way of the Lord; and being fervent in the spirit, he spake and taught diligently the things of the Lord, knowing only the baptism of John.
And he began to speak boldly in the synagogue: whom when Aquila and Priscilla had heard, they took him unto them, and expounded unto him the way of God more perfectly.
And when he was disposed to pass into Achaia, the brethren wrote, exhorting the disciples to receive him: who, when he was come, helped them much which had believed through grace:
For he mightily convinced the Jews, and that publickly, shewing by the scriptures that Jesus was Christ.
And it came to pass, that, while Apollos was at Corinth, Paul having passed through the upper coasts came to Ephesus: and finding certain disciples,
1 Corinthians
Now this I say, that every one of you saith, I am of Paul; and I of Apollos; and I of Cephas; and I of Christ.
Titus
Bring Zenas the lawyer and Apollos on their journey diligently, that nothing be wanting unto them.
