Leviticus 14:42-44

New King James Version

⁴² Then they shall take other stones and put them in the place of those stones, and he shall take other mortar and plaster the house.

⁴³ “Now if the plague comes back and breaks out in the house, after he has taken away the stones, after he has scraped the house, and after it is plastered, ⁴⁴ then the priest shall come and look; and indeed if the plague has spread in the house, it is ^(A)an active leprosy in the house. It is unclean.
