Leviticus 14:33-42

GOD spoke to Moses and Aaron: “When you enter the land of Canaan, which I’m giving to you as a possession, and I put a serious fungus in a house in the land of your possession, the householder is to go and tell the priest, ‘I have some kind of fungus in my house.’ The priest is to order the house vacated until he can come to examine the fungus, so that nothing in the house is declared unclean. When the priest comes and examines the house, if the fungus on the walls of the house has greenish or rusty swelling that appears to go deeper than the surface of the wall, the priest is to walk out the door and shut the house up for seven days. On the seventh day he is to come back and conduct another examination; if the fungus has spread in the walls of the house, he is to order that the stones affected by the fungus be torn out and thrown in a garbage dump outside the city. He is to make sure the entire inside of the house is scraped and the plaster that is removed be taken away to the garbage dump outside the city. Then he is to replace the stones and replaster the house.
