John 21:20-23

New Matthew Bible

²⁰ Peter turned about and saw the disciple whom Jesus loved following, who also had leaned on his breast at supper and said, Lord, who is it that will betray you? ²¹ When Peter saw him he said to Jesus, Lord, what about this man?

²² Jesus said to him, If I desire him to remain till I come, what is that to you? Follow me.

²³ Then there went out a saying among the brethren that that disciple would not die. But Jesus did not say to him that he would not die, but, If I desire him to remain till I come, what is that to you?
