Here ya go.
Acts 19:15 And the evil spirit answered and said, “Jesus I know, and Paul I know; but who are you?” Then the man in whom the evil spirit was leaped on them, overpowered them, and prevailed against them, so that they fled out of that house naked and wounded. 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.

That passage has been used by colonial systems as permission to destroy and brutally supress other belief systems throughout the world. No wonder Christians have such a bad reputation.
