John 12:38-41

38 that the word of Isaiah the prophet might be fulfilled, which he said, `Lord, who gave credence to our report? and the arm of the Lord -- to whom was it revealed?'

39 Because of this they were not able to believe, that again Isaiah said,

40 `He hath blinded their eyes, and hardened their heart, that they might not see with the eyes, and understand with the heart, and turn back, and I might heal them;'

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