John 21:16-18
21:16 Jesus said a second time, “Simon, son of John, do you love me?” He replied, “Yes, Lord, you know I love you.” Jesus told him, “Shepherd my sheep.”
21:17 Jesus said a third time, “Simon, son of John, do you love me?” Peter was distressed that Jesus asked him a third time, “Do you love me?” and said, “Lord, you know everything. You know that I love you.” Jesus replied, “Feed my sheep.
21:18 I tell you the solemn truth, when you were young, you tied your clothes around you and went wherever you wanted, but when you are old, you will stretch out your hands, and others will tie you up and bring you where you do not want to go.”
