John 21:15-17

15 So when they had dined, Jesus said to Simon Peter, Simon, son of Jonas, love you me more than these? He said to him, Yes, Lord; you know that I love you. He said to him, Feed my lambs.

16 He said to him again the second time, Simon, son of Jonas, love you me? He said to him, Yes, Lord; you know that I love you. He said to him, Feed my sheep.

17 He said to him the third time, Simon, son of Jonas, love you me? Peter was grieved because he said to him the third time, Love you me? And he said to him, Lord, you know all things; you know that I love you. Jesus said to him, Feed my sheep.
