1 Corinthians 5:10-11
10 I did not mean the immoral people of this world or the greedy(A) and swindlers(B) or idolaters; otherwise you would have to leave the world.(C)
11 But now I am writing(a) you not to associate with anyone who claims to be a believer(b)(D) who is sexually immoral or greedy, an idolater or verbally abusive, a drunkard(E) or a swindler. Do not even eat with such a person.
