Acts 19:17-20

This became known both to all Jews and Greeks dwelling in Ephesus; and fear fell on them all, and the name of the Lord Jesus was magnified. And many who had believed came confessing and telling their deeds. Also, many of those who had practiced magic brought their books together and burned them in the sight of all. And they counted up the value of them, and it totaled fifty thousand pieces of silver. So the word of the Lord grew mightily and prevailed.
