'Disciple Whom Jesus Loved' in the Bible

Then said that disciple whom Jesus loved to Peter, It is the Lord! Then Simon Peter, when he heard that it was the Lord, girt his coat round him, (for he was stripped,) and threw himself into the sea.

Now Peter, turning about, saw the disciple whom Jesus loved following; who also at the supper reclined on his bosom, and said, Lord, which is the person who betrayeth thee?
