Numbers 16:41

37 “Tell Eleazar son of Aaron the priest to remove the censers from the flames and to scatter the coals far away, because the censers are holy.

38 As for the censers of those who sinned at the cost of their own lives, hammer them into sheets to overlay the altar, for these were presented before the LORD, and so have become holy. They will serve as a sign to the Israelites.”

39 So Eleazar the priest took the bronze censers brought by those who had been burned up, and he had them hammered out to overlay the altar,

40 just as the LORD commanded him through Moses. This was to be a reminder to the Israelites that no outsider who is not a descendant of Aaron should approach to offer incense before the LORD, lest he become like Korah and his followers.

41 The next day the whole congregation of Israel grumbled against Moses and Aaron, saying, “You have killed the LORD’s people!”

42 But when the congregation gathered against them, Moses and Aaron turned toward the Tent of Meeting, and suddenly the cloud covered it and the glory of the LORD appeared.

43 Then Moses and Aaron went to the front of the Tent of Meeting,

44 and the LORD said to Moses,

45 “Get away from this congregation so that I may consume them in an instant.” And Moses and Aaron fell facedown.
