Numbers 6:9-12

9“If someone suddenly dies near him, defiling his consecrated head, he must shave his head on the day of his purification; he is to shave it on the seventh day.

10On the eighth day he is to bring two turtledoves or two young pigeons to the priest at the entrance to the tent of meeting.

11The priest is to offer one as a sin offering and the other as a burnt offering to make atonement on behalf of the Nazirite, since he incurred guilt because of the corpse. On that day he is to consecrate his head again.

12He is to rededicate his time of consecration to the Lord and to bring a year-old male lamb as a guilt offering. But do not count the initial period of consecration because it became defiled.
