Christ, our High Priest, in Revelation: Matthew Henry

1. He was clothed with a garment down to the foot, a princely and priestly robe, denoting righteousness and honour. 2. He was girt about with a golden girdle, the breast-plate of the high-priest, on which the names of his people are engraven; he was ready girt to do all the work of a Redeemer.
