John 12:38-41

38 That the saying of Isaias the prophet might be fulfilled, which he said: Lord, who hath believed our hearing? And to whom hath the arm of the Lord been revealed?

39 Therefore they could not believe, because Isaias 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.

41 These things said Isaias, when he saw his glory, and spoke of him.
