Numbers 16:37-38

³⁷Command thou to Eleazar, the son of Aaron, the priest, that he take, or gather up, the censers that lie in the burning, and that he scatter the fire hither and thither; for those censers be hallowed (or for those censers be holy)

³⁸in the deaths of (these) sinners; and that he bring forth those censers into plates, and nail them to the altar, for incense is offered in those to the Lord, and those be hallowed, that the sons of Israel see them for a sign and a memorial. (even without the deaths of these sinners; and that he make those censers into plates, and then nail them to the altar, for incense was offered in them to the Lord, and so they be holy; and then the Israelites shall see them as a sign and as a reminder.)
