Acts 19
10 Ref This continued for two years, so that all those who lived in Asia heard the word of the Lord Jesus, both Jews and Greeks.
11 Ref God worked special miracles by the hands of Paul,
12 Ref so that even handkerchiefs or aprons were carried away from his body to the sick, and the evil spirits went out.
13 Ref But some of the itinerant Jews, exorcists, took on themselves to name over those who had the evil spirits the name of the Lord Jesus, saying, "We adjure you by Jesus whom Paul preaches."
14 There were seven sons of one Sceva, a Jewish chief priest, who did this.
15 Ref The evil spirit answered, "Jesus I know, and Paul I know, but who are you?"
16 Ref The man in whom the evil spirit was leaped on them, and overpowered them, and prevailed against them, so that they fled out of that house naked and wounded.
17 Ref This became known to all, both Jews and Greeks, who lived at Ephesus. Fear fell on them all, and the name of the Lord Jesus was magnified.
18 Ref Many also of those who had believed came, confessing, and declaring their deeds.
19 Ref Many of those who practiced magical arts brought their books together and burned them in the sight of all. They counted the price of them, and found it to be fifty thousand pieces of silver.{The 50,000 pieces of silver here probably referred to 50,000 drachmas. If so, the value of the burned books was equivalent to about 160 man-years of wages for agricultural laborers}
20 Ref So the word of the Lord was growing and becoming mighty.
