13– 15. ‘ On the other hand as regards the rest of you, Brothers, we exhort you not to fail in doing the right thing, but to persevere in your honourable course. And in order that you may do this, there is nothing for it but to mark the man who is disregarding what we have said in this Epistle, and not in any way to associate with him, in order that thereby he may be shamed. And yet in saying this, we need hardly caution you that you are not to treat him as if he were in any sense an enemy, but rather to counsel him as a brother.’ 13. Ὑμεῖςδέ] ‘ But you’— whatever may have been the conduct of others. Thdt.: μὴνικήσῃτὴνὑμετέρανφιλοτιμίανἡἐκείνωνμοχθηρία. μὴἐνκακήσητε] Ἐνκακέω (for form, WH.2 Notes p. 157 f.) from κακός ‘ cowardly’ is found elsewhere in N.T. only in Luke 18:1, 2 Corinthians 4:1; 2 Corinthians 4:16, Galatians 6:9, Ephesians 3:13 : cf. Polyb. 4:19. 10 τὸμὲνπέμπειντὰςβοηθείας ... ἐνεκάκησαν ‘ they omitted through cowardice to send assistance.’ For the use of the aor. subj. in 2nd pers. after μή, which is comparatively rare in Paul, see Moulton Prolegg. p. 122 ff. καλοποιοῦντες] ‘ doing the fair, the noble thing’ rather than ‘ conferring benefits’ (ἀγαθοποιοῦντες): cf. the double exhortation in 1 Timothy 6:18 ἀγαθοεργεῖν, πλουτεῖνἐνἔργοιςκαλοῖς. The verb καλοποιέω is not found elsewhere in the N.T. (for similar compounds, Lob. Phryn. p. 199 f.), but for the thought see Galatians 6:9 τὸδὲκαλὸνποιοῦντεςμὴἐνκακῶμεν, where, as here, καλός carries with it the thought not only of what is right in itself (I. 5:21 note), but of what is perceived to be right (1 Timothy 5:25 τὰκαλὰπρόδηλα), and consequently exercises an attractive power. See further for this sense of καλός the interesting discussion by Lock, St Paul p. 117 ff.
