LEVITICO 14:8

E colui che si purifica lavi i suoi vestimenti, e radasi tutti i peli, e lavisi con acqua; e sarà netto; poi potrà entrar nel campo; ma dimori sette giorni fuor del suo padiglione.

And he that is to be cleansed shall wash his clothes, and shave off all his hair, and wash himself in water, that he may be clean: and after that he shall come into the camp, and shall tarry abroad out of his tent seven days.
