John 21:20-22

20Peter, turning around, saw the 1disciple whom Jesus loved following them; the one who also had 2leaned back on His bosom at the supper and said, “Lord, who is the one who betrays You?”

21So Peter seeing him said to Jesus, “Lord, and what about this man?”

22Jesus said to him, “If I want him to remain 3until I come, what is that to you? You 4follow Me!”
