Leviticus 14:33-42

The LORD further spoke to Moses and Aaron, saying, “When you come into the land of Canaan, which I am giving you as a possession, and I put a mark of leprosy on a house in your land, then the one who owns the house shall come and tell the priest, ‘I have seen something that looks like a mark of leprosy in my house.’ The priest shall order that they empty the house before he goes in to examine the mark, so that everything in the house will not have to be declared unclean; afterward he shall go in to see the house. He shall examine the mark, and if the mark on the walls of the house has greenish or reddish depressions and appears deeper than the surface, the priest shall go out of the house, to the doorway, and quarantine the house for seven days. The priest shall return on the seventh day and look; and if the mark has spread on the walls of the house, he shall order them to tear out the contaminated stones and throw them into an unclean place outside the city. He shall have the entire inside area of the house scraped, and the plaster that is scraped off shall be dumped in an unclean place outside the city. Then they shall take new stones and replace the [contaminated] stones, and he shall take plaster and replaster the house.
