Leviticus 14:44

40 he must order that the contaminated stones be pulled out and thrown into an unclean place outside the city.

41 And 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.

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

43 If the mildew reappears in the house after the stones have been torn out and the house has been scraped and replastered,

44 the priest must come and inspect it. If the mildew has spread in the house, it is a destructive mildew; the house is unclean.

45 It must be torn down with its stones, its timbers, and all its plaster, and taken outside the city to an unclean place.

46 Anyone who enters the house during any of the days that it is closed up will be unclean until evening.

47 And anyone who sleeps in the house or eats in it must wash his clothes.

48 If, however, the priest comes and inspects it, and the mildew has not spread after the house has been replastered, he shall pronounce the house clean, because the mildew is gone.
