1 Corinthians 5:9-13

5:9 I wrote you in my letter not to associate with sexually immoral people. 5:10 In no way did I mean the immoral people of this world, or the greedy and swindlers and idolaters, since you would then have to go out of the world. 5:11 But now I am writing to you not to associate with anyone who calls himself a Christian who is sexually immoral, or greedy, or an idolater, or verbally abusive, or a drunkard, or a swindler. Do not even eat with such a person. 5:12 For what do I have to do with judging those outside? Are you not to judge those inside? 5:13 But God will judge those outside. Remove the evil person from among you.
