Leviticus 14:39-41

New International Version - UK

³⁹ On the seventh day the priest shall return to inspect the house. If the mould has spread on the walls, ⁴⁰ he is to order that the contaminated stones be torn out and thrown into an unclean place outside the town. ⁴¹ He must have all the inside walls of the house scraped and the material that is scraped off dumped into an unclean place outside the town.
