Leviticus 14:43-45

43And if the plague come again, and break out in the house, after that he hath taken out the stones, and after he hath scraped the house, and after it is plastered; 44then the priest shall come in and look; and, behold, if the plague be spread in the house, it is a fretting leprosy in the house: it is unclean. 45And he shall break down the house, the stones of it, and the timber thereof, and all the mortar of the house; and he shall carry them forth out of the city into an unclean place.
