Then G-d spoke to Moses and Aaron saying, “When you enter the land of Canaan and I inflict leprosy upon a house there, the owner shall come and tell the priest of the affliction. The priest must examine the house and pronounce the home clean or unclean. The unclean parts must be removed and replaced with clean materials. If the whole house is unclean, the house shall be torn down and its materials shall be taken to an unclean place outside the city. The house is to be rebuilt with clean materials. “The priest will inspect the house again. If the priest pronounces the house clean of leprosy, then the priest is to perform a cleansing ritual for the house.
