Acts 19:13-19

13Then certain of the vagabond Jews, exorcists, took upon them to call over them who had evil spirits the name of the Lord Jesus, saying, We adjure you by Jesus whom Paul preacheth. 14And there were seven sons of one Sceva, a Jew, and chief of the priests, who did so. 15And the evil spirit answered and said, Jesus I know, and Paul I know; but who are ye? 16And the man in whom the evil spirit was leaped on them, and overcame them, and prevailed against them, so that they fled out of that house naked and wounded. 17And this was known to all the Jews and Greeks also dwelling at Ephesus; and fear fell on them all, and the name of the Lord Jesus was magnified. 18And many that believed came, and confessed, and showed their deeds. 19Many also of them who practised magic brought their books together, and burned them before all men : and they counted the price of them, and found it fifty thousand pieces of silver.
