John 21:15-22

So when they had eaten breakfast, Jesus said to Simon Peter, “Simon, son of Jonah, do you love Me more than these?” He said to Him, “Yes, Lord; You know that I love You.” He said to him, “Feed My lambs.” He said to him again a second time, “Simon, son of Jonah, do you love Me?” He said to Him, “Yes, Lord; You know that I love You.” He said to him, “Tend My sheep.” He said to him the third time, “Simon, son of Jonah, do you love Me?” Peter was grieved because He said to him the third time, “Do you love Me?” And he said to Him, “Lord, You know all things; You know that I love You.” Jesus said to him, “Feed My sheep. Most assuredly, I say to you, when you were younger, you girded yourself and walked where you wished; but when you are old, you will stretch out your hands, and another will gird you and carry you where you do not wish.” This He spoke, signifying by what death he would glorify God. And when He had spoken this, He said to him, “Follow Me.” Then Peter, turning around, saw the disciple whom Jesus loved following, who also had leaned on His breast at the supper, and said, “Lord, who is the one who betrays You?” Peter, seeing him, said to Jesus, “But Lord, what about this man?” Jesus said to him, “If I will that he remain till I come, what is that to you? You follow Me.”
