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.
