John 12:37-40

Williams(i) 37 Although He had performed so many wonder-works right before their eyes, they did not believe in Him, 38 so that the utterance of the prophet Isaiah was fulfilled: "Lord, who has believed what they heard from us? And to whom has the mighty arm of the Lord been shown?" 39 So they could not believe, for Isaiah again has said: 40 "He has blinded their eyes and benumbed their hearts, so that they cannot see with their eyes and understand with their hearts, and turn to me to cure them."
