Acts 18:22-26

²²And when he had landed at Cæsarea, he went up and saluted the church, and went down to Antioch.

²³And having spent some time there, he departed, and went through the region of Galatia, and Phrygia, in order, establishing all the disciples.

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

²⁵This man had been instructed in the way of the Lord; and being fervent in spirit, he spake and taught accurately the things concerning Jesus, knowing only the baptism of John:

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