Leviticus 14:45-47

⁴⁵And he shall break down the house, the stones of it, and the timber thereof, and all the morter 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.
