'Disciple Whom Jesus Loved' in the Bible

Therefore that disciple whom Jesus loved saith to Peter, It is the Lord. Simon Peter therefore, hearing that it was the Lord, girded on his outer garment, for he had on nothing but his under one, and threw himself into the lake.

Peter, turning round, seeth the disciple whom Jesus loved following,who also at supper leaned back on his breast, and said, Lord, who is he that betrayeth thee?
