Numbers 16:38

35 Fire came forth from Yahweh, and devoured the two hundred fifty men who offered the incense.

36 Yahweh spoke to Moses, saying,

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

38 even the censers of these sinners against their own lives; and let them be made beaten plates for a covering of the altar: for they offered them before Yahweh; therefore they are holy; and they shall be a sign to the children of Israel.

39 Eleazar the priest took the brazen censers, which those who were burnt had offered; and they beat them out for a covering of the altar,

40 to be a memorial to the children of Israel, to the end that no stranger, who isn`t of the seed of Aaron, comes near to burn incense before Yahweh; that he not be as Korah, and as his company: as Yahweh spoke to him by Moses.

41 But on the next day all the congregation of the children of Israel murmured against Moses and against Aaron, saying, You have killed the people of Yahweh.
