9 I wrote vnto you in an Epistle, not to company with fornicators.
10 Yet not altogether with the fornicatours of this world, or with the couetous, or extortioners, or with idolaters; for then must yee needs goe out of the world.
11 But now I haue written vnto you, not to keepe company, if any man that is called a brother bee a fornicator, or couetous, or an idolater, or a railer, or a drunkard, or an extortioner: with such a one, no, not to eate.
12 For what haue I to doe to iudge them also that are without? doe not ye iudge them that are within?
13 But them that are without, God iudgeth. Therefore put away from among your selues that wicked person.
