Context
21Peter seeing him saith to Jesus, Lord, and what this man
22Jesus saith unto him, If I will that he tarry till I come, what to thee? follow thou me.
23Then 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 to thee?
24This is the disciple which testifieth of these things, and wrote these things: and we know that his testimony is true.
25And there are also many other things which Jesus did, the which, if they should be written every one, I suppose that even the world itself could not contain the books that should be written. Amen.
