Acts 18:24-28

24Now a Jew named Apollos, a native of Alexandria, came to Ephesus. He was an eloquent and cultured man, and well versed in the [Hebrew] Scriptures.

25This man had been instructed in the way of the Lord, and being spiritually impassioned, he was speaking and teaching accurately the things about Jesus, though he knew only the baptism of John;

26and he began to speak boldly and fearlessly in the synagogue. But when Priscilla and Aquila heard him, they took him aside and explained more accurately to him the way of God [and the full story of the life of Christ].

27And when Apollos wanted to go across to Achaia (southern Greece), the brothers encouraged him and wrote to the disciples, [urging them] to welcome him gladly. When he arrived, he was a great help to those who, through grace, had believed and had followed Jesus as Lord and Savior,

28for he powerfully refuted the Jews in public discussions, proving by the Scriptures that Jesus is the Christ (the Messiah, the Anointed).
