Leviticus 14:4-20

the priest will order that two live clean birds,  cedar wood,  scarlet  yarn, and hyssop  be brought for the one who is to be cleansed. Then the priest will order that one of the birds be slaughtered over fresh water in a clay pot. He is to take the live bird together with the cedar wood, scarlet yarn, and hyssop, and dip them all into the blood of the bird that was slaughtered over the fresh water. He will then sprinkle the blood seven times on the one who is to be cleansed from the skin disease. He is to pronounce him clean and release the live bird over the open countryside.  The one who is to be cleansed must wash his clothes, shave off all his hair, and bathe with water; he is clean. Afterward he may enter the camp, but he must remain outside his tent for seven days. He is to shave off all his hair again on the seventh day: his head, his beard, his eyebrows, and the rest of his hair. He is to wash his clothes and bathe himself with water; he is clean. “On the eighth day he must take two unblemished  male lambs, an unblemished year-old ewe lamb, a grain offering of six quarts  of fine flour mixed with olive oil, and one-third of a quart  of olive oil. The priest who performs the cleansing will place the person who is to be cleansed, together with these offerings, before the Lord at the entrance to the tent of meeting. The priest is to take one male lamb and present it as a guilt offering,  along with the one-third quart of olive oil, and he will present them as a presentation offering  before the Lord. He is to slaughter the male lamb at the place in the sanctuary area where the sin offering  and burnt offering  are slaughtered,  for like the sin offering, the guilt offering belongs to the priest;  it is especially holy.  The priest is to take some of the blood from the guilt offering and put it on the lobe of the right ear of the one to be cleansed, on the thumb of his right hand, and on the big toe of his right foot.  Then the priest will take some of the one-third quart of olive oil and pour it into his left palm. The priest will dip his right finger into the oil in his left palm and sprinkle some of the oil with his finger seven times before the Lord. From the oil remaining in his palm the priest will put some on the lobe of the right ear of the one to be cleansed, 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.  What is left of the oil in the priest’s palm he is to put on the head of the one to be cleansed. In this way the priest will make atonement for him before the Lord. The priest is to sacrifice the sin offering and make atonement for the one to be cleansed from his uncleanness.  Afterward he will slaughter the burnt offering. The priest is to offer the burnt offering and the grain offering on the altar. The priest will make atonement for him, and he will be clean.
