When thou wast young - When in early life thou didst gird thyself, etc. The Jews, in walking or running, girded their outer garments around them, that they might not be impeded. See the notes at Matthew 5:38-41.

Thou girdedst - The expression here denotes freedom. He did as he pleased - he girded himself or not he went or remained, as he chose. Perhaps the expression refers rather to that time than to the previous period of Peter's life. "Thou being now young or in the vigor of life, hast just girded thyself and come freely to the shore." In either case the Saviour intimates that at the end of his life he would not be thus free.

When thou shalt be old - Ancient writers say that Peter was put to death about thirty-four years after this. His precise age at that time is not known.

Thou shalt stretch forth thy hands - When Peter was put to death, we are told that he requested that he might be crucified with his head downward, saying that he who had denied his Lord as he had done was not worthy to die as he did. This expression of Christ may intimate the readiness of Peter thus to die. Though he was not at liberty as when he was young, though bound by others, yet he freely stretched out his hands on the cross, and was ready to give up his life.

Another shall gird thee - Another shall bind thee. The limbs of persons crucified were often bound instead of being nailed, and even the body was sometimes girded to the cross. See the notes at Matthew 27:35.

Carry thee ... - Shall bear thee, or shall compel thee to go to prison and to death. This is not said to intimate that Peter would be unwilling to suffer martyrdom, but it stands opposed to the freedom of his early life. Though willing when compelled to do it, yet he would not seek it; and though he would not needlessly expose himself to it, yet he would not shrink from it when it was the will of God.

Thou shalt stretch forth thy hands - Wetstein observes that it was a custom at Rome to put the necks of those who were to be crucified into a yoke, and to stretch out their hands and fasten them to the end of it; and having thus led them through the city they were carried out to be crucified. See his note on this place. Thus then Peter was girded, chained, and carried whither he would not - not that he was unwilling to die for Christ; but he was a man - he did not love death; but he loved his life less than he loved his God.

Verily, verily, I say unto thee,.... A way of speaking often used by Christ, when about to deliver anything of considerable moment, partly to raise the attention, and partly for the more strong asseveration of what is spoken; and may have reference both to what went before, confirming Peter's declaration of his love, which would be demonstrated by dying for him, and the testimony of his omniscience, by foretelling his death, and the kind of it; and to what follows after, which contains an account of Peter in his younger years, and a prophecy of what should befall him in old age:

when thou wast young; not that he was old now, and capable he was of doing, and he did do but just now, what our Lord ascribes to his younger years:

thou girdest thyself, and walkest whither thou wouldst; that is, he could put on his clothes himself, and gird them about him with a girdle, as was the custom of the eastern nations, who usually wore long garments; and as he, a little before, had girt his fisher's coat about him, and walked where he pleased; denoting the liberty of his will in things natural and civil, which every man is possessed of, though not in things spiritual, without the grace of God; and also his power of doing what was most grateful to him, without being hindered by, or obliged to ask the leave of others:

but when thou shalt be old; implying, that he should live to a good old age, and be continued to be useful and serviceable in the cause of Christ, in preaching his Gospel, and feeding his lambs and sheep, as he did; for he lived to the times of Nero (c), under whom he suffered, about forty years after this:

thou shalt stretch forth thy hands, and another shall gird thee. This refers not so much to an inability through old age to gird himself, and therefore should stretch forth his hands, that another might with more ease do it for him, and which would be the reverse of his former and present case; for the word gird is used in another sense than before, and signifies the binding of him as, a prisoner with cords, or chains; so "girding", with the Jews, is the same as , "tying and binding" (d): but either to the stretching out of his hands upon the cross, when he should be girt and bound to that; for persons were sometimes fastened to the cross with cords, and not always with nails (e): or, as others think, to his carrying of his cross on his shoulders, with his hands stretched out and bound to the piece of wood which went across; though his being girded or bound may as well be thought to follow the former, as this: indeed, what is added best suits with the latter,

and carry thee whither thou wouldst not; to a painful, cruel, shameful, and accursed death, the death of the cross; not that Peter in spirit would be unwilling to die for Christ, nor was he; but it signifies, that he should die a death disagreeable to the flesh.

Young (νεώτερος)

Literally, younger. Peter was apparently of middle age. See Matthew 8:14.

Thou girdedst thyself (ἐζώννυες σεαυτὸν)

The word may have been suggested by Peter's girding his fisher's coat round him. The imperfect tense signifies something habitual. Thou wast wont to clothe thyself and to come and go at will.

Walkedst (περιεπάτεις)

Literally, walkedst about. Peculiarly appropriate to describe the free activity of vigorous manhood.

Stretch forth thy hands

The allusion to the extending of the hands on the cross, which some interpreters have found here, is fanciful. It is merely an expression for the helplessness of age.

Whither thou wouldest not

According to tradition Peter suffered martyrdom at Rome, and was crucified with his head downward.

{3} Verily, verily, I say unto thee, When thou wast young, thou {c} girdedst thyself, and walkedst whither thou wouldest: but when thou shalt be old, thou shalt stretch forth thy hands, and another shall {d} gird thee, and carry thee whither thou wouldest {e} not.

(3) The violent death of Peter is foretold.

(c) Those that took long trips, especially in the east and in those places where the people used long garments, needed to be girded and fastened up.

(d) He meant that kind of girding which is used with captives, when they are bound fast with cords and chains, as one would say, Now you gird yourself as you think best, to go where you want to go, but the time will come when you will not gird yourself with a girdle, but another will bind you with chains, and carry you where you would not.

(e) Not that Peter suffered anything for the truth of God against his will, for we read that he came with joy and gladness when he returned from the council where he was whipped, but because this will comes not from the flesh, but from the gift of the Spirit who is given to us from above, therefore he shows that there should be a certain striving and conflict or repugnancy, which also is in us, in all our sufferings as touching the flesh.

21:18 When thou wast young, thou girdest thyself. Peter had denied his Master to save his own life. Now that he is reinstated in the old confidence and charged with the Master's work, he is told that he will be called on to die for it. He will be girded, not with a girdle, but with bonds, and he shall be led where he would not, unto death.

21:18 When thou art old - He lived about thirty - six years after this: another shall gird thee - They were tied to the cross till the nails were driven in; and shall carry thee - With the cross: whither thou wouldest not - According to nature; to the place where the cross was set up.

18, 19. When thou wast young-embracing the whole period of life to the verge of old age.

thou girdedst thyself, and walkedst whither thou wouldest-wast thine own master.

when . old thou shalt stretch forth thine hands-to be bound for execution, though not necessarily meaning on a cross. There is no reason, however, to doubt the very early tradition that Peter's death was by crucifixion.

21:15-19 Our Lord addressed Peter by his original name, as if he had forfeited that of Peter through his denying him. He now answered, Thou knowest that I love thee; but without professing to love Jesus more than others. We must not be surprised to have our sincerity called into question, when we ourselves have done that which makes it doubtful. Every remembrance of past sins, even pardoned sins, renews the sorrow of a true penitent. Conscious of integrity, Peter solemnly appealed to Christ, as knowing all things, even the secrets of his heart. It is well when our falls and mistakes make us more humble and watchful. The sincerity of our love to God must be brought to the test; and it behoves us to inquire with earnest, preserving prayer to the heart-searching God, to examine and prove us, whether we are able to stand this test. No one can be qualified to feed the sheep and lambs of Christ, who does not love the good Shepherd more than any earthly advantage or object. It is the great concern of every good man, whatever death he dies, to glorify God in it; for what is our chief end but this, to die to the Lord, at the word of the Lord?
