John 21:20-22

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.
