Leviticus

⁴²and they shall take other stones, and put them in the place of those stones; and he shall take other mortar, and shall plaister the house. 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 plaistered; 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. ⁴⁶Moreover he that goeth into the house all the while that it is shut up shall be unclean until the even. ⁴⁷And he that lieth in the house shall wash his clothes; and he that eateth in the house shall wash his clothes. ⁴⁸And if the priest shall come in, and look, and, behold, the plague hath not spread in the house, after the house was plaistered; then the priest shall pronounce the house clean, because the plague is healed.
