John 10:18

10:18 No one takes it away from me, but I lay it down of my own free will. I have the authority to lay it down, and I have the authority to take it back again. This commandment I received from my 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?”
