Now some also of the Jewish exorcists who went about, attempted to invoke over them that had evil spirits, the name of the Lord Jesus, saying: I conjure you by Jesus, whom Paul preacheth.
And there were certain men, seven sons of Sceva, a Jew, a chief priest, that did this.
But the wicked spirit, answering, said to them: Jesus I know, and Paul I know; but who are you?
And the man in whom the wicked spirit was, leaping upon them, and mastering them both, prevailed against them, so that they fled out of that house naked and wounded. Acts 19:13 – 16
