Leviticus 14:8-9 - The Seven Days Of Purification
8 The person who is clean is to wash his clothes, shave all his hair, and bathe in water, after which he is to be declared clean. Then he can be brought back to the camp, but he is to remain outside his tent for seven days. 9 On the seventh day, he is to shave the hair on his head, chin, back, and eyebrows. After he has shaved all his hair, washed his clothes, and bathed himself with water, then he will be clean."
