John 16:17

16:17 Then some of his disciples said to one another, “What is the meaning of what he is saying, ‘In a little while you will not see me; again after a little while, you will see me,’ and, ‘because I am going to the Father’?”

John 21:23

21:23 So the saying circulated among the brothers and sisters that this disciple was not going to die. But Jesus did not say to him that he was not going to die, but rather, “If I want him to live until I come back, what concern is that of yours?”
