John 21:15-17

15So when they had dined, Jesus saith to Simon Peter, Simon, son of Jonah, lovest thou me more than these? He saith unto him, Yea, Lord; thou knowest that I love thee. He saith unto him, Feed my lambs. 16He saith to him again the second time, Simon, son of Jonah, lovest thou me? He saith unto him, Yea, Lord; thou knowest that I love thee. He saith unto him, Feed my sheep. 17He saith unto him the third time, Simon, son of Jonah, lovest thou me? Peter was grieved because he said unto him the third time, Lovest thou me? And he said unto him, Lord, thou knowest all things; thou knowest that I love thee. Jesus saith unto him, Feed my sheep.
