Leviticus 14:46-48

New Century Version

⁴⁶ Anyone who goes into that house while it is closed up will be unclean until evening. ⁴⁷ Anyone who eats in that house or lies down there must wash his clothes.

⁴⁸ “Suppose after new stones and plaster have been put in a house, the priest checks it again and the mildew has not spread. Then the priest will announce that the house is clean, because the mildew is gone.
