Acts 18:22-28

When he arrived there he traveled on to Jerusalem to visit the church and pray for them, then he left for Antioch. After spending some time there, Paul continued on through the region of Galatia and Phyrgia in central Turkey. And wherever he went he encouraged and strengthened the believers. A Jewish man by the name of Apollos arrived in Ephesus. He was a native of Alexandria and was recognized as an educated and cultured man. He was powerful in the Scriptures, had accepted Jesus, and had been taught about the Lord. He was spiritually passionate for Jesus and a convincing teacher, although he only knew about the baptism of John. He fearlessly preached in the synagogue. But when Priscilla and Aquila heard Apollos’ teachings, they met with him privately and revealed to him the ways of God more completely. Then Apollos, with the encouragement of the believers, went to the province of Achaia. He took a letter of recommendation from the brothers of Ephesus so his ministry would be welcomed in the region. He was a tremendous help to the believers and caused them to increase in grace. Apollos boldly and publicly confronted the Jews, vigorously debating them, proving undeniably from the Scriptures that Jesus was the Messiah.
