Leviticus 14:1-9

Then the LORD spoke to Moses, saying, “This shall be the law of the leper in the day of his cleansing. Now he shall be brought to the priest, and the priest shall go out to the outside of the camp. Thus the priest shall look, and if the infection of leprosy has been healed in the leper, then the priest shall give orders to take two live clean birds and cedar wood and a scarlet string and hyssop for the one who is to be cleansed. The priest shall also give orders to slay the one bird in an earthenware vessel over 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 that was slain over the running water. He shall then sprinkle seven times the one who is to be cleansed from the leprosy and shall pronounce him clean, and shall let the live bird go free over the open field. The one to be cleansed shall then wash his clothes and shave off all his hair and bathe in water and be clean. Now afterward, he may enter the camp, but he shall stay outside his tent for seven days. It will be on the seventh day that he shall shave off all his hair: he shall shave his head and his beard and his eyebrows, even all his hair. He shall then wash his clothes and bathe his body in water and be clean.
