Leviticus 14:6-8

New Catholic Bible

⁶ He is to take the live bird and dip the cedar wood, the scarlet yarn, the hyssop, and the live bird in the blood of the bird that was killed over the fresh water. ⁷ He shall sprinkle the one who is to be declared cleansed seven times. He will then release the live bird in the open fields. ⁸ The person who is being cleansed shall wash his clothes, shave off all his hair, and wash himself with water. He will then be considered to be clean. Thereafter he may come into the camp, but he shall stay outside of his tent for seven days.
