Leviticus 14:39-41

New Century Version

³⁹ On the seventh day the priest must come back and check the house. If the mildew has spread on the walls of the house, ⁴⁰ the priest must order the people to tear out the stones with the mildew on them. They should throw them away, at a certain unclean place outside the city. ⁴¹ Then the priest must have all the inside of the house scraped. The people must throw away the plaster they scraped off the walls, at a certain unclean place outside the city.
