Numbers 16:39; Numbers 16:40

39 So Eleazar the priest took the bronze censers which the men who were burned had offered, and they hammered them out as a plating for the altar,

40 as a reminder to the sons of Israel that no layman who is not of the descendants of Aaron should come near to burn incense before the LORD ; so that he will not become like Korah and his company -just as the LORD had spoken to him through Moses.
