John 21:20-23 - Peter And The Other Disciple Jesus Loved
20 Peter turned round, and saw the disciple whom Jesus loved following--the one who at the supper leant back on the Master's shoulder, and asked him who it was that would betray him. 21 Seeing him, Peter said to Jesus: "Master, what about this man?"
22 "If it is my will that he should wait till I come," answered Jesus, "what has that to do with you? Follow me yourself."
23 So the report spread among the Brethren that that disciple was not to die; yet Jesus did not say that he was not to die, but said "If it is my will that he should wait till I come, what has that to do with you?"
