Romans 16:18

οἱ γὰρ κ.τ.λ. The warning is against men who claimed to be true servants of Christ and were not; cf. 2 Corinthians 11:13 : therefore Judaising Christians, not necessarily themselves originally Jews.

τῇ ἑαυτῶν κοιλίᾳ. Cf. John 7:38; Philippians 3:19 (metaph. only in N.T.) = selfish desires and objects in the widest sense. He does not say ἑαυτοῖς because they are not even serving their own true interests.

διὰ τῆς χρ. The ‘fair speech’ employed by them or characteristic of them; cf. Galatians 3:1; Galatians 4:17. S. H. qu. Jul. Capitol. Pertinax 13, χρ. eum appellantes qui bene loqueretur et male faceret.

εὐλογίας seems to get a bad meaning here by its connexion with χρ. S. H. qu. Aesop Fab. 229, p. 150 ed. Av. In N.T. elsewhere always of ‘blessing.’ Plat. Rep. 400 D of fine speech, in a good sense.

τῶν� = simple, guileless, and therefore unsuspicious; combined with εὐήθης Diod. Sic. ap. Wetstein;)[332] πανοῦργος Dio Cass., ib[333]; cf. Proverbs 1:4; Hebrews 7:26. S. Paul is careful not to suggest that they have as yet any hold upon the Church.
