Quotation · Isaiah 53:1
Go to Isaiah 53:1John quotes it when he says that many did not believe in Jesus, though he had done so many signs (12:37). John begins with “Lord,” which is not in the Hebrew.
Formula: ἵνα ὁ λόγος Ἠσαΐου τοῦ προφήτου πληρωθῇ ὃν εἶπεν “so that the word of Isaiah the prophet might be fulfilled, which he spoke” (John 12:38)

Greek of the New Testament: ἵνα ὁ λόγος Ἠσαΐου τοῦ προφήτου πληρωθῇ ὃν εἶπεν Κύριε τίς ἐπίστευσεν τῇ ἀκοῇ ἡμῶν καὶ ὁ βραχίων κυρίου τίνι ἀπεκαλύφθη
Hebrew (Masoretic text): מִי הֶאֱמִין לִשְׁמֻעָתֵנוּ וּזְרוֹעַ יְהוָה עַל מִי נִגְלָתָה
Septuagint (Isaiah 53:1 in the Septuagint numbering): Kύριε, τίς ἐπίστευσεν τῇ ἀκοῇ ἡμῶν; καὶ ὃ Κυρίου τίνι ἀπεκαλύφθη;
The Greek of the NT matches the Septuagint word for word in 7 consecutive words: “τίς ἐπίστευσεν τῇ ἀκοῇ ἡμῶν καὶ ὁ.”
