Leviticus 14:43-45

43“But if the mildew reappears after all the stones have been replaced and the house has been scraped and replastered,

44the priest must return and inspect the house again. If he finds that the mildew has spread, the walls are clearly contaminated with a serious mildew, and the house is defiled.

45It must be torn down, and all its stones, timbers, and plaster must be carried out of town to the place designated as ceremonially unclean.
