Leviticus 14:37-42

37So he shall look at the spot, and if the spot on the walls of the house has greenish or reddish depressions and appears deeper than the 1surface, 38the priest shall come out of the house, to the 2doorway, and 3quarantine the house for seven days. 39Then the priest shall return on the seventh day and 4make an inspection. If the spot has indeed spread on the walls of the house, 40the priest shall order them to pull out the stones with the spot on them and throw them away 5at an unclean place outside the city. 41And he shall have the house scraped all around 6inside, 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 the discarded stones, and he shall take other plaster and replaster the house.
