For because they desired His life above all things, they could not hear of His death, and as they knew him to be not only a spotless man, but also very God, they thought He could in no wise die. And whenever in the parables, which they frequently heard Him utter, He said any thing concerning His Passion, they believed it to be spoken allegorically, and referred to something else. Hence it follows, And this saying was hid from them, neither knew they the things which were spoken. But the Jews, who conspired against His life, knew that He spoke concerning His Passion, when he said, The Son of man must be lifted up; therefore said they, We have heard in our law that Christ abideth for ever, and how sayest thou the Son of man must be lifted up?
