38. so that the word of Isaiah the prophet would be fulfilled. He said, “Lord, who has believed our message, and to whom has the arm of the Lord been revealed?”

39. For this reason they could not believe, because again Isaiah said,

40. “He has blinded their eyes and hardened their heart, so that they would not see with their eyes and understand with their heart, and turn to me, and I would heal them.”

41. Isaiah said these things because he saw Christ’s glory, and spoke about him.
