Thematic Bible: Charlatan

But there were also some wandering Jewish exorcists who undertook to invoke the name of Jesus over those who had the evil spirits, saying, "I command you by that Jesus whom Paul preaches." There were seven sons of one Sceva, a Jew of high-priestly family, who were doing this. "Jesus I know," the evil spirit answered, "and Paul I have heard of, but who are you?" read more.
And the man in whom the evil spirit was sprang on two of them, over-mastered them both, and treated them with such violence, that they fled from the house stripped of their clothes and wounded. All the people of Ephesus, Jews as well as Greeks, came to know of this. There was widespread terror, and they began to hold the name of the Lord Jesus in high honour.
