Acts 18:26-28
18:26 He began to speak out fearlessly in the synagogue, but when Priscilla and Aquila heard him, they took him aside and explained the way of God to him more accurately.
18:27 When Apollos wanted to cross over to Achaia, the brothers encouraged him and wrote to the disciples to welcome him. When he arrived, he assisted greatly those who had believed by grace,
18:28 for he refuted the Jews vigorously in public debate, demonstrating from the scriptures that the Christ was Jesus.
