Leviticus 14:43

And if the plague come again, and break out in the house,.... In the above signs of it:

after that he hath taken away the stones; which were infected, or ordered them to be taken away:

and after he hath scraped the house; so that there seemed to be no remains of the plague:

and after it is plastered; to prevent if possible any return of it, but in vain.
