Leviticus 14:45-47

⁴⁵He shall break down the house, its stones, and its timber, and all the house’s mortar. He shall carry them out of the city into an unclean place.

⁴⁶“Moreover he who goes into the house while it is shut up shall be unclean until the evening.

⁴⁷He who lies down in the house shall wash his clothes; and he who eats in the house shall wash his clothes.
