Now a Jew named Apollos, an Alexandrian by birth, an eloquent man, came to Ephesus; and he was mighty in the Scriptures. 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; 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. And when he wanted to go across to Achaia, the brethren encouraged him and wrote to the disciples to welcome him; and when he had arrived, he greatly helped those who had believed through grace, for he powerfully refuted the Jews in public, demonstrating by the Scriptures that Jesus was the Christ .
Acts 18:24-28
"When the unclean spirit goes out of a man, it passes through waterless places seeking rest, and not finding any, it says, 'I will return to my house from which I came.' "And when it comes, it finds it swept and put in order. "Then it goes and takes along seven other spirits more evil than itself, and they go in and live there; and the last state of that man becomes worse than the first." While Jesus was saying these things, one of the women in the crowd raised her voice and said to Him, "Blessed is the womb that bore You and the breasts at which You nursed." But He said, "On the contrary, blessed are those who hear the word of God and observe it."
