Numbers 16:38-40

New Revised Standard Version Catholic Edition

³⁸ For the censers of these sinners have become holy at the cost of their lives. Make them into hammered plates as a covering for the altar, for they presented them before the Lord and they became holy. Thus they shall be a sign to the Israelites. ³⁹ So Eleazar the priest took the bronze censers that had been presented by those who were burned; and they were hammered out as a covering for the altar— ⁴⁰ a reminder to the Israelites that no outsider, who is not of the descendants of Aaron, shall approach to offer incense before the Lord, so as not to become like Korah and his company—just as the Lord had said to him through Moses.
