Romans 4:12

καὶ πατέρα περιτομῆς. περ. probably abstr. for concrete, = τῶν περιτεμνομένων.

τοῖς οὐκ ἐκ κ.τ.λ. Among the circumcised only those are sons of Abraham who follow in the steps of the faith which he had before he was circumcised. This is obviously the meaning, but requires the assumption of a primitive error in text. Hort suggests καὶ αὐτοῖς for καὶ τοῖς; W. H., appendix, ad loc[119]; cf. S. H. and Giff. The alternatives are to accept Hort’s emendation or to omit τοῖς before στοιχοῦσιν.

[119] ad loc. ad locum
