Apollos was a Jewish Christian from Alexandria, Egypt. Highly educated, he was a powerful speaker and debater. Apollos traveled to Ephesus and spoke boldly about Jesus Christ in the synagogue, although Aquila and Priscilla (#34) had to instruct him more accurately in the ways of God (Acts 18:24-28, 19:1-7).
Apollos went to Corinth (Acts 18:27-28) and later became an important ministry partner with Paul in Ephesus (1 Corinthians 3:6, 4:6, 16:12). Some Bible scholars have suggested that Apollos was possibly the writer of the letter of Hebrews.
