Leviticus 14:3-9

³and the priest shall go out to a place outside of the camp. Then the priest shall look, and if the leprous infection has been healed in the person with leprosy, ⁴then the priest shall give orders to take two live clean birds, cedar wood, a scarlet string, and hyssop for the one who is to be cleansed. ⁵The priest shall also give orders to slaughter the one bird in an earthenware vessel over running water. ⁶As for the live bird, he shall take it together with the cedar wood, the scarlet string, and the hyssop, and shall dip them and the live bird in the blood of the bird that was slaughtered over the running water. ⁷He 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. ⁸The one to be cleansed shall then wash his clothes and shave off all his hair, and bathe in water and be clean. And afterward he may enter the camp, but he shall stay outside his tent for seven days. ⁹Then it shall 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.
