John 21:15-17

And when they had eaten, Jesus saith to Simon Peter, Simon of John, lovest thou me more than these? He saith to him, Yea, Lord, thou knowest that I love thee. Jesus saith to him, Feed thou my lambs. Again he saith to him, Simon of John, lovest thou me? He saith to him, Yea, Lord, thou knowest that I love thee. He saith to him, Feed thou my lambs. He saith to him the third time, Simon of John, lovest thou me? Peter was heavy, [or sorry], for he said to him the third time, Lovest thou me, and he saith to him, Lord, thou knowest all things; thou knowest that I love thee. Jesus saith to him, Feed my sheep.
