John 21:15-17

15 When therefore they had dined, Jesus saith to Simon Peter: Simon, son of John, lovest thou me more than these? He saith to him: Yea, Lord, thou knowest that I love thee. He saith to him: Feed my lambs.

16 He saith to him again: Simon, son of John, lovest thou me? He saith to him: yea, Lord, thou knowest that I love thee. He saith to him: Feed my lambs.

17 He said to him the third time: Simon, son of John, lovest thou me? Peter was grieved because he had said to him the third time: Lovest thou me? And he said to him: Lord, thou knowest all things: thou knowest that I love thee. He said to him: Feed my sheep.
