Leviticus 14:46-57

46Moreover, whoever goes into the house during the time that he has 1quarantined it, becomes 2unclean until evening. 47Likewise, whoever lies down in the house shall wash his clothes, and whoever eats in the house shall wash his clothes.

48“If, on the other hand, the priest comes in and 3makes an inspection and the mark has not indeed spread in the house after the house has been replastered, then the priest shall pronounce the house clean because the mark has 4not reappeared. 49To cleanse the house then, he shall take 5two birds and cedar wood and a 6scarlet string and hyssop, 50and he shall slaughter the one bird in an earthenware vessel over 7running water. 51Then he shall take the cedar wood and the 8hyssop and the 9scarlet string, with the live bird, and dip them in the blood of the slain bird as well as in the 10running water, and sprinkle the house seven times. 52He shall thus cleanse the house with the blood of the bird and with the 11running water, along with the live bird and with the cedar wood and with the hyssop and with the 12scarlet string. 53However, he shall let the live bird go free outside the city into the open field. So he shall make atonement for the house, and it will be clean.”

54This is the law for any mark of leprosy--even for a 13scale, 55and for the 14leprous garment or house, 56and 15for a swelling, and for a scab, and for a bright spot-- 57to teach 16when they are unclean and 17when they are clean. This is the law of leprosy.
