5 Bible Verses about No Dealings

I have written to you in the letter not to associate with lewd persons;

And if any one obey not our word by this letter, note that man, and do not keep company with him, that he may be ashamed;

but now I write to you, not to associate with any one professing to be a brother, if he is lewd or covetous, or an idolater, or a reviler, or a drunkard, or an extortioner: with such a one not even to eat.
