Leviticus 14:48

And if the priest shall come in, and look [upon it]
That is, on the seventh day of the second week of its being shut up: and, behold, the plague hath not spread in the house, after the house
was plastered; (See Gill on Leviticus 14:42): then the priest shall pronounce the house clean;
fit to be inhabited, and so no more to be shut up, but free for use as before: because the plague is healed;
the infection being wholly removed by taking out the stones, scraping, and plastering the house, and so an entire stop put to the spread of it.
