Leviticus 14:42
And they shall take other stones, and put them in the place of those stones; and he shall take other morter, and shall plaister the house. And they shall take other stones, and put them in the place of those stones; and he shall take other morter, and shall plaister the house.
The command to remove defiled stones, set other stones in their place, and replaster with fresh mortar belongs to the directions given by God to Moses concerning houses. Those directions established orderly care and cleanliness as a required standard.
