Leviticus 14

¹The Lord spoke to Moses, saying, ²“This shall be the law of the leprous person for the day of his cleansing. He shall be brought to the priest, ³and the priest shall go out of the camp, and the priest shall look. Then, if the case of leprous disease is healed in the leprous person, ⁴the priest shall command them to take for him who is to be cleansed two live clean birds and cedarwood and scarlet yarn and hyssop. ⁵And the priest shall command them to kill one of the birds in an earthenware vessel over fresh water. ⁶He shall take the live bird with the cedarwood and the scarlet yarn and the hyssop, and dip them and the live bird in the blood of the bird that was killed over the fresh water. ⁷And he shall sprinkle it seven times on him who is to be cleansed of the leprous disease. Then he shall pronounce him clean and shall let the living bird go into the open field. ⁸And he who is to be cleansed shall wash his clothes and shave off all his hair and bathe himself in water, and he shall be clean. And after that he may come into the camp, but live outside his tent seven days. ⁹And on the seventh day he shall shave off all his hair from his head, his beard, and his eyebrows. He shall shave off all his hair, and then he shall wash his clothes and bathe his body in water, and he shall be clean.
¹⁰“And on the eighth day he shall take two male lambs without blemish, and one ewe lamb a year old without blemish, and a grain offering of three tenths of an ephah of fine flour mixed with oil, and one log of oil. ¹¹And the priest who cleanses him shall set the man who is to be cleansed and these things before the Lord, at the entrance of the tent of meeting. ¹²And the priest shall take one of the male lambs and offer it for a guilt offering, along with the log of oil, and wave them for a wave offering before the Lord. ¹³And he shall kill the lamb in the place where they kill the sin offering and the burnt offering, in the place of the sanctuary. For the guilt offering, like the sin offering, belongs to the priest; it is most holy. ¹⁴The priest shall take some of the blood of the guilt offering, and the priest shall put it on the lobe of the right ear of him who is to be cleansed and on the thumb of his right hand and on the big toe of his right foot. ¹⁵Then the priest shall take some of the log of oil and pour it into the palm of his own left hand ¹⁶and dip his right finger in the oil that is in his left hand and sprinkle some oil with his finger seven times before the Lord. ¹⁷And some of the oil that remains in his hand the priest shall put on the lobe of the right ear of him who is to be cleansed and on the thumb of his right hand and on the big toe of his right foot, on top of the blood of the guilt offering. ¹⁸And the rest of the oil that is in the priest’s hand he shall put on the head of him who is to be cleansed. Then the priest shall make atonement for him before the Lord. ¹⁹The priest shall offer the sin offering, to make atonement for him who is to be cleansed from his uncleanness. And afterward he shall kill the burnt offering. ²⁰And the priest shall offer the burnt offering and the grain offering on the altar. Thus the priest shall make atonement for him, and he shall be clean.
²¹“But if he is poor and cannot afford so much, then he shall take one male lamb for a guilt offering to be waved, to make atonement for him, and a tenth of an ephah of fine flour mixed with oil for a grain offering, and a log of oil; ²²also two turtledoves or two pigeons, whichever he can afford. The one shall be a sin offering and the other a burnt offering. ²³And on the eighth day he shall bring them for his cleansing to the priest, to the entrance of the tent of meeting, before the Lord. ²⁴And the priest shall take the lamb of the guilt offering and the log of oil, and the priest shall wave them for a wave offering before the Lord. ²⁵And he shall kill the lamb of the guilt offering. And the priest shall take some of the blood of the guilt offering and put it on the lobe of the right ear of him who is to be cleansed, and on the thumb of his right hand and on the big toe of his right foot. ²⁶And the priest shall pour some of the oil into the palm of his own left hand, ²⁷and shall sprinkle with his right finger some of the oil that is in his left hand seven times before the Lord. ²⁸And the priest shall put some of the oil that is in his hand on the lobe of the right ear of him who is to be cleansed and on the thumb of his right hand and on the big toe of his right foot, in the place where the blood of the guilt offering was put. ²⁹And the rest of the oil that is in the priest’s hand he shall put on the head of him who is to be cleansed, to make atonement for him before the Lord. ³⁰And he shall offer, of the turtledoves or pigeons, whichever he can afford, ³¹one for a sin offering and the other for a burnt offering, along with a grain offering. And the priest shall make atonement before the Lord for him who is being cleansed. ³²This is the law for him in whom is a case of leprous disease, who cannot afford the offerings for his cleansing.”

³³The Lord spoke to Moses and Aaron, saying, ³⁴“When you come into the land of Canaan, which I give you for a possession, and I put a case of leprous disease in a house in the land of your possession, ³⁵then he who owns the house shall come and tell the priest, ‘There seems to me to be some case of disease in my house.’ ³⁶Then the priest shall command that they empty the house before the priest goes to examine the disease, lest all that is in the house be declared unclean. And afterward the priest shall go in to see the house. ³⁷And he shall examine the disease. And if the disease is in the walls of the house with greenish or reddish spots, and if it appears to be deeper than the surface, ³⁸then the priest shall go out of the house to the door of the house and shut up the house seven days. ³⁹And the priest shall come again on the seventh day, and look. If the disease has spread in the walls of the house, ⁴⁰then the priest shall command that they take out the stones in which is the disease and throw them into an unclean place outside the city. ⁴¹And he shall have the inside of the house scraped all around, and the plaster that they scrape off they shall pour out in an unclean place outside the city. ⁴²Then they shall take other stones and put them in the place of those stones, and he shall take other plaster and plaster the house.
⁴³“If the disease breaks out again in the house, after he has taken out the stones and scraped the house and plastered it, ⁴⁴then the priest shall go and look. And if the disease has spread in the house, it is a persistent leprous disease in the house; it is unclean. ⁴⁵And he shall break down the house, its stones and timber and all the plaster of the house, and he shall carry them out of the city to an unclean place. ⁴⁶Moreover, whoever enters the house while it is shut up shall be unclean until the evening, ⁴⁷and whoever sleeps in the house shall wash his clothes, and whoever eats in the house shall wash his clothes.
⁴⁸“But if the priest comes and looks, and if the disease has not spread in the house after the house was plastered, then the priest shall pronounce the house clean, for the disease is healed. ⁴⁹And for the cleansing of the house he shall take two small birds, with cedarwood and scarlet yarn and hyssop, ⁵⁰and shall kill one of the birds in an earthenware vessel over fresh water ⁵¹and shall take the cedarwood and the hyssop and the scarlet yarn, along with the live bird, and dip them in the blood of the bird that was killed and in the fresh water and sprinkle the house seven times. ⁵²Thus he shall cleanse the house with the blood of the bird and with the fresh water and with the live bird and with the cedarwood and hyssop and scarlet yarn. ⁵³And he shall let the live bird go out of the city into the open country. So he shall make atonement for the house, and it shall be clean.”
⁵⁴This is the law for any case of leprous disease: for an itch, ⁵⁵for leprous disease in a garment or in a house, ⁵⁶and for a swelling or an eruption or a spot, ⁵⁷to show when it is unclean and when it is clean. This is the law for leprous disease.
