Numbers 16:40

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.

41 But on the day after, all the children of Israel made an outcry against Moses and against Aaron, saying, You have put to death the Lord's people.

42 Now when the people had come together against Moses and Aaron, looking in the direction of the Tent of meeting, they saw the cloud covering it, and the glory of the Lord came before their eyes.

43 Then Moses and Aaron came to the front of the Tent of meeting.
