John 21:7 in the King James Version
Therefore that disciple whom Jesus loved saith unto Peter, It is the Lord. Now when Simon Peter heard that it was the Lord, he girt his fisher’s coat unto him, (for he was naked,) and did cast himself into the sea.

6 He said to them, “Cast the net on the right side of the boat, and you will find some.” They cast it therefore, and now they weren’t able to draw it in for the multitude of fish.
7 That disciple therefore whom Jesus loved said to Peter, “It’s the Lord!” So when Simon Peter heard that it was the Lord, he wrapped his coat around himself (for he was naked), and threw himself into the sea.
8 But the other disciples came in the little boat (for they were not far from the land, but about two hundred cubits away), dragging the net full of fish.
