Adam Clarke on 2 Thessalonians 3:11

For we hear that there are some - It is very likely that St. Paul kept up some sort of correspondence with the Thessalonian Church; for he had heard every thing that concerned their state, and it was from this information that he wrote his second epistle.

Disorderly - Ατακτως· Out of their rank - not keeping their own place.

Working not at all - Either lounging at home, or becoming religious gossips; μηδεν εργαζομενους, doing nothing.

Busybodies - Περιεργαζομενους· Doing every thing they should not do - impertinent meddlers with other people's business; prying into other people's circumstances and domestic affairs; magnifying or minifying, mistaking or underrating, every thing; newsmongers and telltales; an abominable race, the curse of every neighborhood where they live, and a pest to religious society. There is a fine paronomasia in the above words, and evidently intended by the apostle.
