John 21:7; John 21:20; John 21:24
That disciple whom Jesus loved said to Peter, "It is the Lord!" When Simon Peter heard that it was the Lord, he put on his clothes, for he was stripped for work, and sprang into the sea.
Peter turned and saw following them the disciple whom Jesus loved, who had lain close to his breast at the supper and had said, "Lord, who is it that is going to betray you?"
This is the disciple who is bearing witness to these things, and who has written these things; and we know that his testimony is true.
