Verily, verily, I say unto you, When you were young, you dressed yourself, and walked where you would: but when you shall be old, you shall stretch forth your hands, and another shall dress you, and carry you where you would not.

John Chrysostom
AD 407
And yet this he did will, and desired; on which account also He has revealed it to him. For since Peter had continually said, I will lay down my life for You John 13:37, and, Though I should die with You, yet will I not deny You Matthew 26:35: He has given him back his desire. What then is the, Whither you will not? He speaks of natural feeling, and the necessity of the flesh, and that the soul is unwillingly torn away from the body. So that even though the will were firm, yet still even then nature would be found in fault. For no one lays aside the body without feeling, God, as I said before, having suitably ordained this, that violent deaths might not be many. For if, as things are, the devil has been able to effect this, and has led ten thousand to precipices and pits; had not the soul felt such a desire for the body, the many would have rushed to this under any common discouragement. The, whither you will not, is then the expression of one signifying natural feeling.
But how after having said, When you were young, does He again say, When you are old? For this is the expression of one declaring that he was not then young; (nor was he; nor yet old, but a man of middle age. ) Wherefore then did He recall to his memory his former life? Signifying, that this is the nature of what belongs to Him. In things of this life the young man is useful, the old useless; but in Mine, He says, not so; but when old age has come on, then is excellence brighter, then is manliness more illustrious, being nothing hindered by the time of life. This He said not to terrify, but to rouse Him; for He knew his love, and that he long had yearned for this blessing. At the same time He declares the kind of death. For since Peter ever desired to be in the dangers which were for His sake, Be of good cheer, He says, I will so satisfy your desire, that, what you suffered not when young, you must suffer when you are old. Then the Evangelist, to rouse the hearer, has added,
