Leviticus 14:36-42

³⁶The priest shall command that they empty the house, before the priest goes in to examine the plague, that all that is in the house not be made unclean. Afterward the priest shall go in to inspect the house.

³⁷He shall examine the plague; and behold, if the plague is in the walls of the house with hollow streaks, greenish or reddish, and it appears to be deeper than the wall,

³⁸then the priest shall go out of the house to the door of the house, and shut up the house seven days.

³⁹The priest shall come again on the seventh day, and look. If the plague has spread in the walls of the house,

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

⁴¹He shall cause the inside of the house to be scraped all over. They shall pour out the mortar that they scraped off outside of the city into an unclean place.

⁴²They shall take other stones, and put them in the place of those stones; and he shall take other mortar, and shall plaster the house.
