Leviticus 14:37-42

37He is to examine the infection, and if the infection in the walls of the house consists of yellowish green or reddish eruptions, and it appears to be deeper than the surface of the wall,

38then the priest is to go out of the house to the doorway of the house and quarantine the house for seven days.

39The priest must return on the seventh day and examine it, and if the infection has spread in the walls of the house,

40then the priest is to command that the stones that had the infection in them be pulled and thrown outside the city into an unclean place.

41Then he is to have the house scraped all around on the inside, and the plaster which is scraped off must be dumped outside the city into an unclean place.

42They are then to take other stones and replace those stones, and he is to take other plaster and replaster the house.
