Leviticus 14:46-57

46And he that goeth into the house as long as it is shut up shall be unclean until the even. 47And he that sleepeth in the house shall wash his garments, and he that eateth in the house shall wash his garments. 48But if the priest shall come in and look, and behold, the plague hath not spread in the house, after the house hath been plastered, the priest shall pronounce the house clean; for the plague is healed. 49And he shall take, to purge the house from the defilement, two birds, and cedar-wood, and scarlet, and hyssop; 50and he shall kill one bird in an earthen vessel over running water; 51and he shall take the cedar-wood and the hyssop and the scarlet, and the living bird, and dip them in the blood of the bird that was killed, and in the running water, and sprinkle the house seven times; 52and he shall purge the house from the defilement with the blood of the bird, and with the running water, and with the living bird, and with the cedar-wood, and with the hyssop, and with the scarlet; 53and he shall let the living bird loose out of the city into the open field; and he shall make atonement for the house, and it is clean. 54This is the law for every sore of leprosy, and for the scall, 55and for the leprosy of garments, and of houses, 56and for the rising, and for the scab, and for the bright spot, 57to teach when there is uncleanness, and when it is purified: this is the law of leprosy.
