39 This is why they were unable to believe, because Isaiah also said:
40 He has blinded their eyes and hardened their hearts, so that they would not see with their eyes or understand with their hearts, and be converted, and I would heal them. c
41 Isaiah said these things becaused he saw His glory and spoke about Him.
