Leviticus 14:39-41

New King James Version

³⁹ And the priest shall come again on the seventh day and look; and indeed if the plague has spread on the walls of the house, ⁴⁰ then the priest shall command that they take away the stones in which is the plague, and they shall cast them into an unclean place outside the city. ⁴¹ And he shall cause the house to be scraped inside, all around, and the dust that they scrape off they shall pour out in an unclean place outside the city.
