John 21:20-23 - Peter And The Other Disciple Jesus Loved
20 Peter turned around and saw that the disciple whom Jesus loved was following??e who at the supper leaned back upon his breast and said, "Lord, who is to betray you?" 21 On catching sight of him, Peter said to Jesus, "Lord, what about him?"
22 "If I choose that he remain until I come," said Jesus, "what is that to you? Do you follow me."
23 Accordingly the report spread among the brothers that this disciple should not die; but Jesus did not say that he was not to die, but said, "If I choose that he remain until I come, what is that to you?"
