Numbers 16:37-38
37
"Speak to Eleazar the son of Aaron the priest, that he take up the censers out of the burning, and scatter 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."
