1 Corinthians 5:11-13

11But actually, I wrote you not to associate with anyone who claims to be a brother or sister and is sexually immoral or greedy, an idolater or verbally abusive, a drunkard or a swindler. Do not even eat with such a person.

12For what business is it of mine to judge outsiders? Don’t you judge those who are inside?

13God judges outsiders. Remove the evil person from among you.
