Numbers 16:38-40

Young's Literal Translation

³⁸ [even] the censers of these sinners against their own souls; and they have made them spread-out plates, a covering for the altar, for they have brought them near before Jehovah, and they are hallowed; and they are become a sign to the sons of Israel.'

³⁹ And Eleazar the priest taketh the brazen censers which they who are burnt had brought near, and they spread them out, a covering for the altar --

⁴⁰ a memorial to the sons of Israel, so that a stranger who is not of the seed of Aaron doth not draw near to make a perfume before Jehovah, and is not as Korah, and as his company, -- as Jehovah hath spoken by the hand of Moses to him.
