John 21:20-23 - Peter And The Other Disciple Jesus Loved
20 Then Peter, turning about, saw the disciple whom Jesus loved following; who also leaned on his breast at supper, and said, Lord, who is he that betrays you? 21 Peter seeing him said to Jesus, Lord, and what shall this man do?
22 Jesus said unto him, If I will that he tarry till I come, what is that to you? you follow me.
23 Then went this saying abroad among the brethren, that that disciple should not die: yet Jesus said not unto him, He shall not die; but, If I will that he tarry till I come, what is that to you?
