Both Matthew, Matthew 27:35, and Mark, Mark 15:24, mention this parting of Christ's garments amongst them, which must be understood of his inward garments; which some tell us might easily be done, because their garments were made up of four parts. But his outward garment, which is called his coat, was all of a piece.
