Leviticus 14:1-9

Then the LORD spoke to Moses, saying, “This shall be the law of the leper on the day of his [ceremonial] cleansing. He shall be brought to the priest [at a meeting place outside the camp]; the priest shall go out of the camp [to meet him]; and the priest shall examine him, and if the leper has been healed of the infection of leprosy, then the priest shall give orders to take two live clean birds and cedar wood and scarlet string and hyssop for the one to be cleansed. [Heb 9:19-22] Next the priest shall order that one of the birds be killed [as a sacrifice] in an earthenware container over [fresh] running water. As for the live bird, he shall take it together with the cedar wood and the scarlet string and the hyssop, and shall dip them and the live bird in the blood of the bird sacrificed over the running water. He shall sprinkle [the blood] seven times on the one to be cleansed from the leprosy and shall pronounce him [ceremonially] clean. Then he shall let the live bird go free over the open field. [Heb 9:13-15] The one to be cleansed shall wash his clothes, shave off all his hair, and bathe in water; and he shall be clean. After that he may come into the camp, but he shall stay outside of his tent for seven days. On the seventh day he shall shave off all his hair: he shall shave his head and his beard and his eyebrows, even all his hair [on his body]. Then he shall wash his clothes and bathe his body in water, and be clean.
