John 21:19-23

This spake he, signifying by what death he should glorify God. And when he had spoken this, he saith unto him, Follow me.

Then Peter, turning about, seeth the disciple whom Jesus loved following; which also leaned on his breast at supper, and said, Lord, which is he that betrayeth thee?

Peter seeing him saith to Jesus, Lord, and what shall this man do?

Jesus saith unto him, If I will that he tarry till I come, what is that to thee? follow thou me.

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 thee?
