John 21:7; John 21:20; John 21:24
Then the disciple Jesus loved said to Peter, “It’s the Lord!” When Simon Peter heard that it was the Lord, he put on his tunic (for he had stripped for work), jumped into the water, and headed to shore.
Peter turned around and saw behind them the disciple Jesus loved—the one who had leaned over to Jesus during supper and asked, “Lord, who will betray you?”
This disciple is the one who testifies to these events and has recorded them here. And we know that his account of these things is accurate.
