Leviticus 14:37-42

37He will examine it, and if the contamination in the walls of the house consists of green or red indentations that appear to be beneath the surface of the wall,

38the priest is to go outside the house to its doorway and quarantine the house for seven days.

39The priest is to return on the seventh day and examine it. If the contamination has spread on the walls of the house,

40the priest must order that the stones with the contamination be pulled out and thrown into an unclean place outside the city.

41He is to have the inside of the house completely scraped, and have the plaster that is scraped off dumped in an unclean place outside the city.

42Then they are to take different stones to replace the former ones and take additional plaster to replaster the house.
