Acts 18:24–26

24 Now a Jew named Apollos, an Alexandrian by birth, an eloquent man, came to Ephesus; and he was mighty in the Scriptures.

25 This man had been instructed in the way of the Lord; and being fervent in spirit, he was speaking and teaching accurately the things concerning Jesus, being acquainted only with the baptism of John;

26 and he began to speak out boldly in the synagogue. But when Priscilla and Aquila heard him, they took him aside and explained to him the way of God more accurately.
