Leviticus 14
8 Ref And he who is to be made clean will have his clothing washed and his hair cut and have a bath, and he will be clean. And after that he will come back to the tent-circle; but he is to keep outside his tent for seven days.
9 Ref And on the seventh day he is to have all the hair cut off his head and his chin and over his eyes--all his hair is to be cut off--and he will have his clothing washed and his body bathed in water and he will be clean.
