Leviticus 14:45-47

⁴⁵And he shall break down the house, its stones, and its timber, and all the mortar of the house: and he shall carry them forth out of the city to an unclean place.

⁴⁶Moreover, he that goeth into the house all the while that it is shut up, shall be unclean until the evening.

⁴⁷And he that lieth in the house shall wash his clothes: and he that eateth in the house shall wash his clothes.
