Numbers 6:6-11

6Throughout the days of his separation to the LORD, he must not go near a dead body. 7Even if his father or mother or brother or sister should die, he is not to defile himself, because the symbol of consecration to his God is upon his head. 8Throughout the time of his separation, he is holy to the LORD.

9If someone suddenly dies in his presence and defiles his consecrated head of hair, he must shave his head on the day of his cleansing—the seventh day. 10On the eighth day he must bring two turtledoves or two young pigeons to the priest at the entrance to the Tent of Meeting. 11And the priest is to offer one as a sin offering1 and the other as a burnt offering to make atonement for him, because he has sinned by being in the presence of the dead body. On that day he must consecrate his head again.
