Acts 18:24-27

24Now a Jewish man named Apollos, a native of Alexandria, came to Ephesus. He was a learned man, well versed in the Scriptures.

25He had been instructed in the way of the Lord. With a fervent spirit, he was speaking and teaching accurately the facts about Yeshua—while only being acquainted with the immersion of John.

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

27When Apollos wanted to cross over to Achaia, the brothers encouraged him and wrote to the disciples to welcome him. Upon arrival, he greatly helped those who by grace had believed.
