RKJNT(i)
9 I wrote to you in a letter not to keep company with the sexually immoral:
10 Not at all meaning the immoral of this world, or the covetous, or swindlers, or idolaters; for then you would have to go out of the world.
11 But now I write to you not to keep company with any man who is called a brother if he is sexually immoral, or covetous, or an idolater, or a slanderer, or a drunkard, or an swindler; with such a one do not even eat.
12 For what have I to do with judging those who are outside? are you not to judge those who are within?
13 Those who are outside God judges. Put out from among yourselves the wicked person.
