Acts 19:17-20

And this became known to all, both Jews and Greeks, that dwelt at Ephesus; and fear fell upon them all, and the name of the Lord Jesus was magnified. Many also of them that had believed came, confessing, and declaring their deeds. And not a few of them that practised magical arts brought their books together and burned them in the sight of all; and they counted the price of them, and found it fifty thousand pieces of silver. So mightily grew the word of the Lord and prevailed.
