Numbers 16:36-40

36And Yhwh spake unto Moses, saying, 37Speak unto Eleazar the son of Aaron the priest, that he take up the censers out of the burning, and scatter thou the fire yonder; for they are hallowed. 38The censers of these sinners against their own souls, let them make them broad plates for a covering of the altar: for they offered them before Yhwh, therefore they are hallowed: and they shall be a sign unto the children of Israel. 39And Eleazar the priest took the brasen censers, wherewith they that were burnt had offered; and they were made broad plates for a covering of the altar: 40To be a memorial unto the children of Israel, that no stranger, which is not of the seed of Aaron, come near to offer incense before Yhwh; that he be not as Korah, and as his company: as Yhwh said to him by the hand of Moses.
