Acts 19:18-20

¹⁸Many, too, of those who had become believers in Christ came with a full confession of their practices;

¹⁹while a number of people, who had practiced magic, collected their books and burnt them publicly; and on reckoning up the price of these, they found it amounted to fifty thousand silver coins.

²⁰So irresistibly did the Lord's message spread and prevail.
