“But if when the priest comes and conducts his examination, he finds that the fungus has not spread after the house has been replastered, the priest is to declare that the house is clean; the fungus is cured. He then is to purify the house by taking two birds, some cedar wood, scarlet thread, and hyssop. He will slaughter one bird over fresh water in a clay pot. Then he will take the cedar wood, the hyssop, the scarlet thread, and the living bird, dip them in the blood of the killed bird and the fresh water and sprinkle the house seven times, cleansing the house with the blood of the bird, the fresh water, the living bird, the cedar wood, the hyssop, and the scarlet thread. Last of all, he will let the living bird loose outside the city in the open field. He has made atonement for the house; the house is clean.
