John 21:7, 18-22

That disciple therefore whom Jesus loved saith unto Peter, It is the Lord. So when Simon Peter heard that it was the Lord, he girt his coat about him (for he was naked), and cast himself into the sea.

Verily, verily, I say unto thee, When thou wast young, thou girdedst thyself, and walkedst whither thou wouldest: but when thou shalt be old, thou shalt stretch forth thy hands, and another shall gird thee, and carry thee whither thou wouldest not. Now this he spake, signifying by what manner of death he should glorify God. And when he had spoken this, he saith unto him, Follow me. Peter, turning about, seeth the disciple whom Jesus loved following; who also leaned back on his breast at the supper, and said, Lord, who is he that betrayeth thee? Peter therefore seeing him saith to Jesus, Lord, and what shall this man do? Jesus saith unto him, If I will that he tarry till I come, what is that to thee? follow thou me.
