21:7 Then the disciple whom Jesus loved said to Peter, “It is the Lord!” So Simon Peter, when he heard that it was the Lord, tucked in his outer garment (for he had nothing on underneath it), and plunged into the sea.
21:20 Peter turned around and saw the disciple whom Jesus loved following them. (This was the disciple who had leaned back against Jesus’ chest at the meal and asked, “Lord, who is the one who is going to betray you?”)
21:24 This is the disciple who testifies about these things and has written these things, and we know that his testimony is true.
