Acts 18:24-28

Now there came to Ephesus a Jew named Apollos, a native of Alexandria. He was an eloquent man, well-versed in the scriptures. He had been instructed in the Way of the Lord; and he spoke with burning enthusiasm and taught accurately the things concerning Jesus, though he knew only the baptism of John. He began to speak boldly in the synagogue; but when Priscilla and Aquila heard him, they took him aside and explained the Way of God to him more accurately. And when he wished to cross over to Achaia, the believers encouraged him and wrote to the disciples to welcome him. On his arrival he greatly helped those who through grace had become believers, for he powerfully refuted the Jews in public, showing by the scriptures that the Messiah is Jesus.
