31 And the Lord said: Simon, Simon, behold Satan hath desired to have you, that he may sift you as wheat: 32 But I have prayed for thee, that thy faith fail not: and thou, being once converted, confirm thy brethren. (St. Luke 22)
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. (St. John 21)
