Numbers 16:37

37.Speak unto Eleazar the son of Aaron. Since there is no manifestation of God’s wrath so conspicuous as not to be forgotten too often by man’s stupidity, God was willing to anticipate this evil, and set up a monument for posterity, lest the recollection of this memorable judgment should ever be obscured. He commands, therefore, that a covering for the altar should be made of the censers, in order that none should rashly intrude himself to make the sacred offerings. When He calls them “hallowed,” some understand that it was sinful to transfer them to profane purposes, because they had once been devoted to the service of God. I am, however, rather of opinion that they were set apart (sacratas) as things accursed (anathemata.) Thus the fire which had been upon them is scattered afar, in order that the altar should be cleansed from its pollution. Although, however, there was the same pollution in the censers, yet God would have them preserved as accursed, so that all posterity might understand that none but the priests were to be admitted to the sacrifices. Nor is it superfluous for Him to speak of the rebels as having acted criminally “against their own souls;” but it was in order that the memory of their punishment might be inn manner engraved upon those brazen enclosures, in order to awaken continued dread.
