Leviticus 14:39-46

³⁹And the priest shall come again on the seventh day; and if he see, that, behold, the plague have spread in the walls of the house:

⁴⁰Then shall the priest command that they break out the stones on which the plague is; and they shall cast them forth without the city on an unclean place.

⁴¹And the house he shall cause to be scraped within round about; and they shall pour out the rubbish that they have scraped off without the city on an unclean place.

⁴²And they shall take other stones, and put them into the place of these stones; and other mortar shall he take, and shall plaster the house.

⁴³And if the plague come again, and break out in the house, after he hath taken away the stones, and after the house hath been scraped, and after it hath been plastered:

⁴⁴Then shall the priest come; and if he see that, behold, the plague have spread in the house, it is a corrosive leprosy in the house; it is unclean.

⁴⁵And he shall break down the house, its stones, and the timbers thereof, and all the mortar of the house; and he shall carry them forth to without the city, unto an unclean place.

⁴⁶And he that goeth into the house, all the days that it is locked up, shall be unclean until the evening.
