Acts 19:17-20

All of the people in Ephesus were awestruck, both Jews and non-Jews, when they heard about what had happened. Great fear fell over the entire city, and the authority of the name of Jesus was exalted. Many believers publicly confessed their sins and disclosed their secrets. Large numbers of those who had been practicing magic took all of their books and scrolls of spells and incantations and publicly burned them. When the value of all the books and scrolls was calculated, it all came to several million dollars. The power of God caused the word to spread, and the people were greatly impacted.
