Leviticus 14:40-45

40he must order that the contaminated stones be pulled out and thrown into an unclean place outside the city. 41And he shall have the inside of the house scraped completely and the plaster that is scraped off dumped into an unclean place outside the city.

42So different stones must be obtained to replace the contaminated ones, as well as additional mortar to replaster the house.

43If the mildew reappears in the house after the stones have been torn out and the house has been scraped and replastered, 44the priest must come and inspect it.

If the mildew has spread in the house, it is a destructive mildew; the house is unclean. 45It must be torn down with its stones, its timbers, and all its plaster, and taken outside the city to an unclean place.
