Leviticus 14:43-57

“But if the mildew reappears after all the stones have been replaced and the house has been scraped and replastered, the priest must return and inspect the house again. If he finds that the mildew has spread, the walls are clearly contaminated with a serious mildew, and the house is defiled. It must be torn down, and all its stones, timbers, and plaster must be carried out of town to the place designated as ceremonially unclean. Those who enter the house during the period of quarantine will be ceremonially unclean until evening, and all who sleep or eat in the house must wash their clothing. “But if the priest returns for his inspection and finds that the mildew has not reappeared in the house after the fresh plastering, he will pronounce it clean because the mildew is clearly gone. To purify the house the priest must take two birds, a stick of cedar, some scarlet yarn, and a hyssop branch. He will slaughter one of the birds over a clay pot filled with fresh water. He will take the cedar stick, the hyssop branch, the scarlet yarn, and the live bird, and dip them into the blood of the slaughtered bird and into the fresh water. Then he will sprinkle the house seven times. When the priest has purified the house in exactly this way, he will release the live bird in the open fields outside the town. Through this process, the priest will purify the house, and it will be ceremonially clean. “These are the instructions for dealing with serious skin diseases, including scabby sores; and mildew, whether on clothing or in a house; and a swelling on the skin, a rash, or discolored skin. This procedure will determine whether a person or object is ceremonially clean or unclean. “These are the instructions regarding skin diseases and mildew.”
