Leviticus 14:40-45

40he shall order them to tear out the contaminated stones and throw them into an unclean place outside the city.

41He shall have the entire inside area of the house scraped, and the plaster that is scraped off shall be dumped in an unclean place outside the city.

42Then they shall take new stones and replace the [contaminated] stones, and he shall take plaster and replaster the house.

43“If, however, the mark breaks out again in the house after he has removed the stones and has scraped and replastered the house,

44then the priest shall come and look again, and if the mark has spread in the house, it is a malignant leprosy in the house; it is [ceremonially] unclean.

45He shall tear down the house—its stones and its timber and all the plaster of the house—and shall take everything outside the city to an unclean place.
