1 Corinthians 5:9-11 I wrote unto you in an epistle not to company with fornicators:

KJ2000⁽ⁱ⁾ ⁹ I wrote unto you in an epistle not to company with fornicators: ¹⁰ Yet not entirely with the fornicators of this world, or with the covetous, or extortioners, or with idolaters; for then must you needs go out of the world. ¹¹ But now I have written unto you not to keep company, if any man that is called a brother be a fornicator, or covetous, or an idolater, or a railer, or a drunkard, or an extortioner; with such a one no not to eat.
