Acts 19:17-20

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. And many of those who practiced magic brought their books together and began burning them in the sight of everyone; and they added up the prices of the books and found it to be fifty thousand pieces of silver. So the word of the Lord was growing and prevailing mightily.
