Leviticus 14:7-9

7Seven times he shall sprinkle the one to be cleansed of the defiling disease, and then pronounce them clean. After that, he is to release the live bird in the open fields. 8“The person to be cleansed must wash their clothes, shave off all their hair and bathe with water; then they will be ceremonially clean. After this they may come into the camp, but they must stay outside their tent for seven days. 9On the seventh day they must shave off all their hair; they must shave their head, their beard, their eyebrows and the rest of their hair. They must wash their clothes and bathe themselves with water, and they will be clean.
