Numbers 6:6-11

6All the days of his separation to Adonai, he is not to go near a dead body.

7Even if his father, mother, brother or sister should die, he is not to make himself unclean, because his consecration to God is on his head.

8All the days of his separation, he is to be consecrated to Adonai.

9“Now if someone should die suddenly in his presence, thereby defiling his dedicated head, he is to shave his head on the day of his purification—the seventh day.

10Then on the eighth day, he is to bring two doves or two young pigeons to the kohen at the entrance of the Tent of Meeting.

11The kohen is to offer one as a sin offering and the other as a burnt offering. He is to make atonement for him because he sinned through the corpse. He must consecrate his head on the same day.
