And certain ones of the itinerant Jewish exorcists undertook to call the name of the Lord Jesus, over those having evil spirits saying, I adjure you in the name of Jesus whom Paul is preaching.

But the evil spirit responding said to them, I know Jesus, and am acquainted with Paul; but who are you?

And the man in whom was the evil spirit, leaping on them, domineering over both of them, prevailed against them, so that they fled out of that house naked and wounded.
