Numbers 16:37

34 And all Israel round about them went in flight at their cry, For fear, said they, that we go down into the heart of the earth.

35 Then fire came out from the Lord, burning up the two hundred and fifty men who were offering the perfume.

36 And the Lord said to Moses,

37 Say to Eleazar, the son of Aaron the priest, that he is to take out of the flames the vessels with the perfumes in them, turning the fire out of them, for they are holy;

38 And let the vessels of those men, who with their lives have made payment for their sin, be hammered out into plates as a cover for the altar; for they have been offered before the Lord and are holy; so that they may be a sign to the children of Israel.

39 So Eleazar the priest took the brass vessels which had been offered by those who were burned up, and they were hammered out to make a cover for the altar:

40 To be a sign, kept in memory for ever by the children of Israel, that no man who is not of the seed of Aaron has the right of burning spices before the Lord, so that he may not be like Korah and his band: as the Lord said to him by the mouth of Moses.
