Numbers 6:8-12

8All the days of his separation he is holy to Jehovah.

9And if any one die unexpectedly by him suddenly, and he hath defiled the head of his consecration, then he shall shave his head on the day of his cleansing; on the seventh day shall he shave it.

10And on the eighth day he shall bring two turtle-doves, or two young pigeons, to the priest, at the entrance of the tent of meeting.

11And the priest shall offer one for a sin-offering, and the other for a burnt-offering, and make an atonement for him, for that he sinned by the dead person; and he shall hallow his head that same day.

12And he shall [again] consecrate to Jehovah the days of his separation, and shall bring a yearling lamb for a trespass-offering. But the first days are forfeited, for his consecration hath been defiled.
