John 21
16 Ref Again, a second time, he said to him, Simon, son of John, have you any love for me? Yes, Lord, he said, you are certain of my love for you. Then take care of my sheep, said Jesus.
17 Ref He said to him a third time, Simon, son of John, am I dear to you? Now Peter was troubled in his heart because he put the question a third time, Am I dear to you? And he said to him, Lord, you have knowledge of all things; you see that you are dear to me. Jesus said to him, Then give my sheep food.
