33 And the Lord said to Moses and Aaron, 34 When you have come into the land of Canaan, which I give to you for a possession, and I put the disease of leprosy in a house of the land of your possession, 35 Then he who owns the house shall come and tell the priest, It seems to me there is some sort of disease in my house. 36 Then the priest shall command that they empty the house before [he] goes in to examine the disease, so that all that is in the house may not be declared unclean; afterward [he] shall go in to see the house. 37 He shall examine the disease, and if it is in the walls of the house with depressed spots of dark green or dark red appearing beneath [the surface of] the wall, 38 Then the priest shall go out of the door and shut up the house seven days. 39 The priest shall come again on the seventh day and shall look; and if the disease has spread in the walls of the house, 40 He shall command that they take out the diseased stones and cast them into an unclean place outside the city. 41 He shall cause the house to be scraped within round about and the plaster or mortar that is scraped off to be emptied out in an unclean place outside the city. 42 And they shall put other stones in the place of those stones, and he shall plaster the house with fresh mortar.
43 If the disease returns, breaking out in the house after he has removed the stones and has scraped and plastered the house, 44 Then the priest shall come and look, and if the disease is spreading in the house, it is a rotting or corroding leprosy in the house; it is unclean. 45 He shall tear down the house--its stones and its timber and all the plaster or mortar of the house--and shall carry them forth out of the city to an unclean place. 46 Moreover, he who enters the house during the whole time that it is shut up shall be unclean until the evening. 47 And he who lies down or eats in the house shall wash his clothes.
48 But if the priest inspects it and the disease has not spread after the house was plastered, he shall pronounce the house clean, because the disease is healed. 49 He shall take to cleanse the house two birds, cedar wood, scarlet [material], and hyssop; 50 And he shall kill one of the birds in an earthen vessel over running water, 51 And he shall take the cedar wood, and the hyssop, and the scarlet [material], and the living bird, and dip them in the blood of the slain bird and in the running water, and sprinkle the house seven times. 52 And he shall cleanse the house with the blood of the bird, the running water, the living bird, the cedar wood, the hyssop, and the scarlet [material]. 53 But he shall let the living bird go out of the city into the open field; so he shall make atonement for the house, and it shall be clean.
54 This is the law for all kinds of leprous diseases, and mangelike conditions, 55 For the leprosy of a garment or of a house, 56 And for a swelling or an eruption or a scab or a bright spot, 57 To teach when it is unclean and when it is clean. This is the law of leprosy.
