John 21:7; John 21:20; John 21:24

7 Then that disciple whom Jesus loved said to Peter, "It is the Lord!" So Simon Peter, [when he] heard that it was the Lord, tied around himself his outer garment (for he was naked) and threw himself into the sea.
20 Peter turned [and] saw the disciple whom Jesus loved following [them] (who also leaned back on his chest at the dinner and said, "Lord, who is the one betraying you?")
24 This is the disciple who is testifying about these [things], and who has written down these [things]. And we know that his testimony is true.
