OT Prophecy NT Fulfillment
Isaiah 6:9–10a
[9] And he said, Go, and tell this people, Hear ye indeed, but understand not; and see ye indeed, but perceive not.
[10] Make the heart of this people fat, and make their ears heavy, and shut their eyes; lest they see with their eyes, and hear with their ears, and understand with their heart, and convert, and be healed.
John 12:37–40
[37] But though he had done so many miracles before them, yet they believed not on him:
[38] That the saying of Esaias the prophet might be fulfilled, which he spake, Lord, who hath believed our report? and to whom hath the arm of the Lord been revealed?
[39] Therefore they could not believe, because that Esaias said again,
[40] He hath blinded their eyes, and hardened their heart; that they should not see with their eyes, nor understand with their heart, and be converted, and I should heal them.
Tanakh – Neviim – Isaiah 6:9–10a
[9] And He said: Go, and tell this people: hear ye indeed, but understand not; and see ye indeed, but perceive not.
[10] Make the heart of this people fat, and make their ears heavy, and shut their eyes; lest they, seeing with their eyes, and hearing with their ears, and understanding with their heart, return, and be healed.
Hebrew OT – Isaiah 6:9–10a
[6:9] וַיֹּאמֶר לֵךְ וְאָמַרְתָּ לָעָם הַזֶּה
שִׁמְעוּ שָׁמוֹעַ וְאַל־תָּבִינוּ
וּרְאוּ רָאוֹ וְאַל־תֵּדָעוּ
[6:10] הַשְׁמֵן לֵב־הָעָם הַזֶּה
וְאָזְנָיו הַכְבֵּד וְעֵינָיו הָשַׁע
פֶּן־יִרְאֶה בְעֵינָיו וּבְאָזְנָיו יִשְׁמָע
וּלְבָבוֹ יָבִין וָשָׁב וְרָפָא לוֹ
