Numbers 16:35-40

35And there came out a fire from Jehovah, and consumed the two hundred and fifty men that had presented incense.

36And Jehovah spoke to Moses, saying,

37Speak to Eleazar the son of Aaron the priest, that he take up the censers out of the burning; and scatter the fire afar; for they are hallowed,

38the censers of these sinners who have forfeited their life; and they shall make them into broad plates for the covering of the altar; for they presented them before Jehovah, therefore they are hallowed; and they shall be a sign unto the children of Israel.

39And Eleazar the priest took the copper censers, which they that were burnt had presented; and they were made broad plates for a covering of the altar:

40as a memorial to the children of Israel, that no stranger who is not of the seed of Aaron come near to burn incense before Jehovah, that he be not as Korah, and as his band, — as Jehovah had said to him through Moses.
