John 12:38-40

38This was to fulfill the word of Isaiah the prophet, who said, “Adonai, who has believed our report? To whom has the arm of Adonai been revealed?”

39For this reason they could not believe, for Isaiah also said,

40“He has blinded their eyes and hardened their hearts, so they might not see with their eyes nor understand with their hearts and turn back, and I would heal them.”
