Leviticus 14:40 KJV

38Then the priest shall go out of the house to the door of the house, and shut up the house seven days:

39And the priest shall come again the seventh day, and shall look: and, behold, if the plague be spread in the walls of the house;

40Then 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:

41And 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:

42And they shall take other stones, and put them in the place of those stones; and he shall take other morter, and shall plaister the house.
