Leviticus 14:39-46

³⁹And the priest shall return on the seventh day and view the house; and, behold, if the plague is spread in the walls of the house,

⁴⁰then the priest shall give orders, and they shall take away the stones in which the plague is, and shall cast them out of the city into an unclean place.

⁴¹And they shall scrape the house within round about, and shall pour out the dust scraped off outside the city into an unclean place.

⁴²And they shall take other scraped stones, and put them in the place of the former stones, and they shall take other plaster and plaster the house.

⁴³And if the plague should return again, and break out in the house after they have taken away the stones and after the house is scraped, and after it has been plastered,

⁴⁴then the priest shall go in and see if the plague is spread in the house: it is a confirmed leprosy in the house, it is unclean.

⁴⁵And they shall take down the house, and its timbers and its stones, and they shall carry out all the mortar without the city into an unclean place.

⁴⁶And he that goes into the house at any time, during its separation, shall be unclean until evening.
