John 21:16-17

16A second time he asked him, “Simon, son of John, do you love me?” “Yes, Lord,” he said to him, “you know that I love you.” “Shepherd my sheep,” he told him.

17He asked him the third time, “Simon, son of John, do you love me?” Peter was grieved that he asked him the third time, “Do you love me?” He said, “Lord, you know everything; you know that I love you.” “Feed my sheep,” Jesus said.
