1 Corinthians 5:11
But now I am writing to you not to spend time with anyone who says he is a brother but lives in sin. Stay away from him if he is sexually immoral or greedy. Stay away if he worships idols or curses people. Stay away if he is a drunk or a cheater. Don't even eat with such a person.
