John 21:21

¹⁹Now he said this, signifying by what kind of death he would glorify God. When he had said this, he said to him, “Follow me.”

²⁰Then Peter, turning around, saw a disciple following. This was the disciple whom Jesus sincerely loved, the one who had also leaned on Jesus’ breast at the supper and asked, “Lord, who is going to betray You?”

²¹Peter seeing him, said to Jesus, “Lord, what about this man?”

²²Jesus said to him, “If I desire that he stay until I come, what is that to you? You follow me.”

²³This saying therefore went out among the brothers, that this disciple wouldn’t die. Yet Jesus didn’t say to him that he wouldn’t die, but, “If I desire that he stay until I come, what is that to you?”
