Numbers 16
39 Eleazar the priest took the brazen censers, which those who were burnt had offered; and they beat them out for a covering of the altar,
40 Ref to be a memorial to the children of Israel, to the end that no stranger, who isn't of the seed of Aaron, comes near to burn incense before Yahweh; that he not be as Korah, and as his company: as Yahweh spoke to him by Moses.
