These sinners against their own souls. — i.e., men who have forfeited their lives by their sin.
Let them make them broad plates... — It was thus that the sacrilegious act of Korah and his company was made the occasion of a permanent warning against all similar profanation of holy things. The altar of burnt-offering had already a covering of brass; but, as the altar was made of wood, an additional covering afforded further security against the fire which was continually burning on it. The censers of Korah and his company were made of brass (Numbers 16:39). Those of Aaron and his sons are thought by some to have been made of silver, but there seems to be no sufficient authority for this supposition; and in Exodus 38:3, where the same Hebrew word is used, but which in the English version is rendered “firepans,” it is said that all the vessels of the altar were made of brass. In the time of Solomon the censers were made of gold (1 Kings 7:50). That used by Aaron on the great day of atonement was of gold. (Comp. Hebrews 9:4; Revelation 8:3.)
