Christ, our High Priest, in Daniel: Matthew Henry

His [Christ's] dress was priestly, for he is the high-priest of our profession, clothed in linen as the high-priest himself was in the day of atonement, that great day; his loins were girded, (in St John's vision his paps were girded) with a golden girdle of the finest gold, that of Uphaz, for every thing about Christ is the best in its kind.
