Acts 19:14-18

Now there were seven sons of Sceva, a Jewish chief priest, doing this.

But the evil spirit responded and said to them, “I recognize Jesus, and I know of Paul, but who are you?”

And the man in whom was the evil spirit, pounced on them and subdued all of them and overpowered them, so that they fled out of that house naked and wounded.

This became known to all who lived in Ephesus, both Jews and Greeks; and fear fell upon them all and the name of the Lord Jesus was being magnified.

Also many of those who had believed kept coming, confessing and disclosing their practices.
