John 12:38; John 12:40; John 12:49

38 This was to fulfill the word of Isaiah the prophet: “Lord, who has believed our message and to whom has the arm of the Lord been revealed?”
40 “He has blinded their eyes and hardened their hearts, so they can neither see with their eyes, nor understand with their hearts, nor turn—and I would heal them.”
49 For I did not speak on my own, but the Father who sent me commanded me to say all that I have spoken.
