John 21:19-22

Moffatt(i) 19 (he said this to indicate the kind of death by which Peter would glorify God); then he added, "Follow me." 20 Peter turned round and saw that the favourite disciple of Jesus was following, the disciple who had leant on his breast at supper and put the question, "Lord, who is to betray you?" 21 So, on catching sight of him, Peter said to Jesus, "And what about him, Lord?" 22 Jesus replied, "If I choose that he should survive till I come back, what does that matter to you? Follow me yourself."
