9-12. If any man die very suddenly by him, and he hath defiled the head of his consecration--Cases of sudden death might occur to make him contract pollution; and in such circumstances he was required, after shaving his head, to make the prescribed offerings necessary for the removal of ceremonial defilement (Le 15:13; Nu 19:11). But by the terms of this law an accidental defilement vitiated the whole of his previous observances, and he was required to begin the period of his Nazaritism afresh. But even this full completion did not supersede the necessity of a sin offering at the close. Sin mingles with our best and holiest performances, and the blood of sprinkling is necessary to procure acceptance to us and our services.
