ἐξ ἐθνῶν] Not ‘of Gentile descent,’ but ‘taken from, belonging to the Gentiles’; comp. Acts 15:23. ἁμαρτωλοί] ‘sinners.’ The word was almost a synonyme for ἔθνη in the religious phraseology of the Jews. See 1 Macc. 2:44, Clem. Hom. 11:16 οὕτως ὡς οὐχὶ Ἰουδαῖος, ἁμαρτωλὸς κ.τ.λ.; and compare Luke 6:32, 33 with Matt. 5:47, and especially Matt. 26:45 with Luke 18:32. Here ἁμαρτωλοὶ is used in preference to ἔθνη, not without a shade of irony, as better enforcing St Paul’s argument.
