TSK · John 19:26

There was at the table reclining in Jesus' bosom one of his disciples, whom Jesus loved.

That disciple therefore whom Jesus loved saith unto Peter, It is the Lord. So when Simon Peter heard that it was the Lord, he girt his coat about him (for he was naked), and cast himself into the sea.

This is the disciple that beareth witness of these things, and wrote these things: and we know that his witness is true.
