Leviticus 14:40-42

40then the priest shall order them to tear out the stones with the mark in them and throw them away 1at an unclean place outside the city. 41He shall have the house scraped all around 2inside, and they shall dump the plaster that they scrape off at an unclean place outside the city. 42Then they shall take other stones and replace those stones, and he shall take other plaster and replaster the house.
