Numbers 16:37-38

³⁷(17:2) Speak unto Elazar the son of Aaron the priest, that he lift up the censers out of the burning, and throw out the fire far away; for they have been hallowed:

³⁸(17:3) The censers of these sinners against their own lives; and they shall make of them broad plates for a covering for the altar; for they brought them near before the Lord, and they have thus become hallowed; and they shall serve for a sign unto the children of Israel.
