Leviticus 14:37-42

37He shall examine the mark, and if the mark on the walls of the house has greenish or reddish depressions and appears deeper than the surface,

38the priest shall go out of the house, to the doorway, and quarantine the house for seven days.

39The priest shall return on the seventh day and look; and if the mark has spread on the walls of the house,

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.
