1 tn The translation “[will] be punished” is given here by BDAG 428 s.v. ζημιόω 2. But the next clause says “he will be delivered” and so “suffering loss” is more likely to refer to the destruction of the “work” by fire or the loss of the reward that could have been gained.
2 tn Or “built up”; This is the same word used in v. 1b. It is used ironically here: The weak person is “built up” to commit what he regards as sin.
3 tc The Byzantine texttype and a few other witnesses (Hc Ψ Ï) essentially duplicate v. 26 at the end of this verse (with γάρ [gar, “for”] in second instead of third position), which itself is a quotation from Ps 24:1 (23:1 LXX). Not only is there a vast number of early, important, and diverse witnesses that lack this extra material (א A B C* D F G H* P 33 81 365 630 1175 1739 1881 2464 latt co), but the quotation seems out of place at this point in the discourse for Paul is here discussing reasons not to partake of food that has been sacrificed to idols. Perhaps scribes felt that since food is from the Lord, to eat meat sacrificed to idols contradicts that belief. Either way, the better witnesses lack the clause which, had it been authentic to v. 28, would have not occasioned such a widespread excision. The evidence is thus compelling for the shorter reading.
