Numbers 16:39

35And there came out a fire from the Lord, and consumed the two hundred and fifty men that offered incense.

36And the Lord 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 the Lord, 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 the Lord; that he be not as Korah, and as his company: as the Lord said to him by the hand of Moses.

41But on the morrow all the congregation of the children of Israel murmured against Moses and against Aaron, saying, Ye have killed the people of the Lord.

42And it came to pass, when the congregation was gathered against Moses and against Aaron, that they looked toward the tabernacle of the congregation: and, behold, the cloud covered it, and the glory of the Lord appeared.

43And Moses and Aaron came before the tabernacle of the congregation.
