Romans 11:8

Greek of the New Testament: καθὼς γέγραπται Ἔδωκεν αὐτοῖς ὁ θεὸς πνεῦμα κατανύξεως ὀφθαλμοὺς τοῦ μὴ βλέπειν καὶ ὦτα τοῦ μὴ ἀκούειν ἕως τῆς σήμερον ἡμέρας

Hebrew (Masoretic text): וְלֹא נָתַן יְהוָה לָכֶם לֵב לָדַעַת וְעֵינַיִם לִרְאוֹת וְאָזְנַיִם לִשְׁמֹעַ עַד הַיּוֹם הַזֶּה

Septuagint (Deuteronomy 29:4 in the Septuagint numbering): καὶ οὐκ ἔδωκεν κύριος ὁ θεὸς ὑμῖν καρδίαν εἰδέναι καὶ ὀφθαλμοὺς βλέπειν καὶ ὦτα ἀκούειν ἕως τῆς ἡμέρας ταύτης.
