John 21:15-22
(15) So when they had finished breakfast, Jesus said to Simon Peter, “Simon, son of John, do you love Me more than these?” He said to Him, “Yes, Lord; You know that I love You.” He said to him, “Tend My lambs.” (16) He said to him again a second time, “Simon, son of John, do you love Me?” He said to Him, “Yes, Lord; You know that I love You.” He said to him, “Shepherd My sheep.” (17) He said to him the third time, “Simon, son of John, 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, “Tend My sheep.(18) wherever you wished; but when you grow old, you will stretch out your hands and someone else will gird you, and bring you where you do not wish to go.” (19) Now this He said, signifying by what kind of death he would glorify God. And when He had spoken this, He said to him, “Follow Me!” (20) Peter, turning around, saw the disciple whom Jesus loved following them; the one who also had leaned back on His bosom at the supper and said, “Lord, who is the one who betrays You?” (21) So Peter seeing him said to Jesus, “Lord, and what about this man?” (22) Jesus said to him, “If I want him to remain until I come, what is that to you? You follow Me!”
