1 Corinthians 5:9-11

Moffatt(i) 9 In my letter I wrote that you were not to associate with the immoral. 10 I did not mean you were literally to avoid contact with the immoral in this world, with the lustful and the thievish, or with idolaters; in that case you would have to leave the world altogether. 11 What I now write is that you are not to associate with any so-called brother who is immoral or lustful or idolatrous or given to abuse or drink or robbery. Associate with him! Do not even eat with him!
