When they had finished eating, Jesus said to Simon Peter, “Simon son of John, do you love me more than these?”
“Yes, Lord,” he said, “you know that I love you.” Jesus said, “Feed my lambs.” Again Jesus said, “Simon son of John, do you love me?
He answered, “Yes, Lord, you know that I love you.” Jesus said, “Take care of my sheep.” The third time he said to him, “Simon son of John, do you love me?”
Peter was hurt because Jesus asked him the third time, “Do you love me?” He said, “Lord, you know all things; you know that I love you.” Jesus said, “Feed my sheep.”
