Acts of the Apostles 18:24-26

Meanwhile, a Jew named Apollos, an eloquent speaker who knew the Scriptures well, had arrived in Ephesus from Alexandria in Egypt. He had been taught the way of the Lord, and he taught others about Jesus with an enthusiastic spirit and with accuracy. However, he knew only about John’s baptism. When Priscilla and Aquila heard him preaching boldly in the synagogue, they took him aside and explained the way of God even more accurately.
