For we hear of some who walk among you in rebellion, who don't work at all, but are busybodies.
Busybodies -- cf. Acts 17:5. Not seen in English, but in the Greek Paul is making a play on words. Words that are related to each other, spelled almost the same way, and come from the same root. A paranomasia, or play on words; "work" and "busybodies" being cognate; so it may be translated, "who have no business, and yet are busy with everybody’s business"
