John 21:20-22

20Peter, turning round, sees the disciple whom Jesus loved following, who also leaned at supper on his breast, and said, Lord, who is it that delivers thee up?

21Peter, seeing him, says to Jesus, Lord, and what [of] this [man]?

22Jesus says to him, If I will that he abide until I come, what [is that] to thee? Follow thou me.
