John 21:22-23

22Jesus said to him, “If I want him to stay alive until I come [again], what is that to you? You follow Me!”

23So this word went out among the brothers that this disciple (John) was not going to die; yet Jesus did not say to him that he was not going to die, but only, “If I want him to stay alive until I come [again], what is that to you?”
