John 12:38-41

38 that the word of Isaiah the prophet might be fulfilled, which he spoke, Lord, who shall believe our report? and to whom has the arm of the Lord been revealed?

39 Therefore they could not believe, because Isaiah said again,

40 He has 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 Isaiah said these things when he saw his glory and spoke of him.
