Leviticus 14:40

36 The priest must order that the house be cleared before he enters it to examine the mildew, so that nothing in the house will become unclean. After this, the priest shall go in to inspect the house.

37 He is to examine the house, and if the mildew on the walls consists of green or red depressions that appear to be beneath the surface of the wall,

38 the priest shall go outside the doorway of the house and close it up for seven days.

39 On the seventh day the priest is to return and inspect the house. If the mildew has spread on the walls,

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.
