Leviticus 14:37-42

37And when he looketh on the plague, and behold, the plague is in the walls of the house, greenish or reddish hollows, and their look is deeper than the surface of the wall,

38then the priest shall go out of the house to the entrance of the house, and shut up the house seven days.

39And the priest shall come again the seventh day, and when he looketh, and behold, the plague hath 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 out of the city, in an unclean place.

41And he shall cause the house to be scraped within round about, and they shall pour out the mortar that they have scraped off, out of the city in an unclean place.

42And they shall take other stones, and put them in the place of those stones; and they shall take other mortar, and shall plaster the house.
