Acts 18:22-28

When he had landed at Caesarea, he went up and greeted the church [at Jerusalem], and then went down to Antioch. After spending some time there, he left and traveled through the territory of Galatia and Phrygia, strengthening and encouraging all the disciples. Now 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. This 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; and 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]. And 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, for he powerfully refuted the Jews in public discussions, proving by the Scriptures that Jesus is the Christ (the Messiah, the Anointed).
