Numbers 6:9-11

9“ ‘If someone dies suddenly in the Nazirite’s presence, thus defiling the hair that symbolizes their dedication, they must shave their head on the seventh day—the day of their cleansing.

10Then on the eighth day they must bring two doves 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 for the Nazirite because they sinned by being in the presence of the dead body. That same day they are to consecrate their head again.
