Leviticus 14:1-8

And Jehovah spake unto Moses, saying, This shall be the law of the leper in the day of his cleansing: he shall be brought unto the priest: and the priest shall go forth out of the camp; and the priest shall look; and, behold, if the plague of leprosy be healed in the leper, then shall the priest command to take for him that is to be cleansed two living clean birds, and cedar wood, and scarlet, and hyssop: and the priest shall command to kill one of the birds in an earthen vessel over running water. As for the living bird, he shall take it, and the cedar wood, and the scarlet, and the hyssop, and shall dip them and the living bird in the blood of the bird that was killed over the running water: and he shall sprinkle upon him that is to be cleansed from the leprosy seven times, and shall pronounce him clean, and shall let go the living bird into the open field. And he that 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 shall come into the camp, but shall dwell outside his tent seven days.
