Acts 19:13-16

Now, there were seven itinerant Jewish exorcists, sons of Sceva the high priest, who took it upon themselves to use the name and authority of Jesus over those who were demonized. They would say, “We cast you out in the name of the Jesus that Paul preaches!” One day, when they said those words, the demon in the man replied, “I know about Jesus, and I recognize Paul, but who do you think you are?” Then the demonized man jumped on them and threw them to the ground, beating them mercilessly. He overpowered the seven exorcists until they all ran out of the house naked and badly bruised.
