Acts 19:13-19

13Now some of the itinerant Jewish exorcists also attempted to pronounce the name of the Lord Jesus over those who had evil spirits, saying, “I command you by the Jesus that Paul preaches!”

14Seven sons of Sceva, a Jewish high priest, were doing this.

15The evil spirit answered them, “I know Jesus, and I recognize Paul — but who are you?”

16Then the man who had the evil spirit jumped on them, overpowered them all, and prevailed against them, so that they ran out of that house naked and wounded.

17When this became known to everyone who lived in Ephesus, both Jews and Greeks, they became afraid, and the name of the Lord Jesus was held in high esteem.

18And many who had become believers came confessing and disclosing their practices,

19while many of those who had practiced magic collected their books and burned them in front of everyone. So they calculated their value and found it to be fifty thousand pieces of silver.
