Leviticus 14:44-46 World English Bible (WEB)
44 then the priest shall come in and look; and behold, if the plague has spread in the house, it is a destructive mildew in the house. It is unclean. 45 He 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.
