John 18:15-27 New Revised Standard Version (NRSV)
Peter Denies Jesus
15 Simon Peter and another disciple followed Jesus. Since that disciple was known to the high priest, he went with Jesus into the courtyard of the high priest, 16 but Peter was standing outside at the gate. So the other disciple, who was known to the high priest, went out, spoke to the woman who guarded the gate, and brought Peter in. 17 The woman said to Peter, “You are not also one of this man’s disciples, are you?” He said, “I am not.” 18 Now the slaves and the police had made a charcoal fire because it was cold, and they were standing around it and warming themselves. Peter also was standing with them and warming himself.
The High Priest Questions Jesus
19 Then the high priest questioned Jesus about his disciples and about his teaching. 20 Jesus answered, “I have spoken openly to the world; I have always taught in synagogues and in the temple, where all the Jews come together. I have said nothing in secret. 21 Why do you ask me? Ask those who heard what I said to them; they know what I said.” 22 When he had said this, one of the police standing nearby struck Jesus on the face, saying, “Is that how you answer the high priest?” 23 Jesus answered, “If I have spoken wrongly, testify to the wrong. But if I have spoken rightly, why do you strike me?” 24 Then Annas sent him bound to Caiaphas the high priest.
Peter Denies Jesus Again
25 Now Simon Peter was standing and warming himself. They asked him, “You are not also one of his disciples, are you?” He denied it and said, “I am not.” 26 One of the slaves of the high priest, a relative of the man whose ear Peter had cut off, asked, “Did I not see you in the garden with him?” 27 Again Peter denied it, and at that moment the cock crowed.
John 21:15-18 New Revised Standard Version (NRSV)
Jesus and Peter
15 When they had finished breakfast, Jesus said to Simon Peter, “Simon son of John, do you love me more than these?” He said to him, “Yes, Lord; you know that I love you.” Jesus said to him, “Feed my lambs.” 16 A second time he said to him, “Simon son of John, do you love me?” He said to him, “Yes, Lord; you know that I love you.” Jesus said to him, “Tend my sheep.” 17 He said to him the third time, “Simon son of John, do you love me?” Peter felt hurt because he said to him the third time, “Do you love me?” And he said to him, “Lord, you know everything; you know that I love you.” Jesus said to him, “Feed my sheep. 18 Very truly, I tell you, when you were younger, you used to fasten your own belt and to go wherever you wished. But when you grow old, you will stretch out your hands, and someone else will fasten a belt around you and take you where you do not wish to go.”
