John 12:39

37But though he had done so many signs before them, yet they didn’t believe in him,

38that the word of Isaiah the prophet might be fulfilled, which he spoke: “Lord, who has believed our report? To whom has the arm of the Lord been revealed?”

39For this cause they couldn’t believe, for Isaiah said again:

40“He has blinded their eyes and he hardened their heart, lest they should see with their eyes, and perceive with their heart, and would turn, and I would heal them.”

41Isaiah said these things when he saw his glory, and spoke of him.
