TSK · John 19:26

One of his disciples, the one Jesus loved, was at the table to the right of Jesus in a place of honor.

Then the disciple whom Jesus loved said to Peter,“It is the Lord!” So Simon Peter, when he heard that it was the Lord, tucked in his outer garment(for he had nothing on underneath it), and plunged into the sea.

A Final Note This is the disciple who testifies about these things and has written these things, and we know that his testimony is true.
