Leviticus 14:42-44

New Century Version

⁴² Then the owner must put new stones in the walls, and he must cover the walls with new clay plaster.

⁴³ “Suppose a person has taken away the old stones and plaster and put in new stones and plaster. If mildew again appears in his house, ⁴⁴ the priest must come back and check the house again. If the mildew has spread in the house, it is a mildew that destroys things; the house is unclean.
