Moreover he that goeth into the house all the while that it is shut up shall be unclean until the even.
And he that lieth in the house shall wash his clothes; and he that eateth in the house shall wash his clothes.Leviticus 14:47 KJV
And 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.Leviticus 14:45 KJV
