Robertson's Word Pictures (NT)
I wrote unto you in my epistle (egraya umin en th epistolh). Not the epistolary aorist, but a reference to an epistle to the Corinthians earlier than this one (our First Corinthians), one not preserved to us. What a "find" it would be if a bundle of papyri in Egypt should give it back to us?
To have no company with fornicators (mh sunanamignusqai pornoiv). Present middle infinitive with mh in an indirect command of a late double compound verb used in the papyri to mix up with (sun-ana-mignusqai, a mi verb). It is in the N.T. only here and verse I Corinthians 5:11; II Thessalonians 3:14 which see. It is used here with the associative instrumental case (pornoiv, from peraw, pernhmi, to sell, men and women who sell their bodies for lust). It is a pertinent question today how far modern views try to put a veneer over the vice in men and women.
