Parallel
Romans 9:29
Nestle 1904 Greek New Testament · Berean Standard Bible
Καὶ καθὼς προείρηκεν Ἠσαΐας Εἰ μὴ Κύριος Σαβαὼθ ἐγκατέλιπεν ἡμῖν σπέρμα ὡς Σόδομα ἂν ἐγενήθημεν καὶ ὡς Γόμορρα ἂν ὡμοιώθημεν
It is just as Isaiah foretold: “Unless the Lord of Hosts had left us descendants, we would have become like Sodom, we would have resembled Gomorrah (note: Isaiah 1:9 (see also LXX)).”
