Then the priest shall command that they take away the stones in which the plague is, and they shall cast them into an unclean place without the city:
And he shall cause the house to be scraped within round about, and they shall pour out the dust that they scrape off without the city into an unclean place:Leviticus 14:41 KJV
And the priest shall come again the seventh day, and shall look: and, behold, if the plague be spread in the walls of the house;Leviticus 14:39 KJV
