1 Corinthians 5:9-11 I wrote to you in a letter not to keep company with the sexually immoral:

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.
