Acts 19
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.
