Numbers 6:6-12 New American Bible (Revised Edition) (NABRE)
6 As long as they are dedicated to the Lord, they shall not come near a dead person. 7 Not even for their father or mother, sister or brother, should they defile themselves, when these die, since their heads bear their dedication to God. 8 As long as they are nazirites they are holy to the Lord.
9 If someone dies very suddenly in their presence, defiling their dedicated heads, they shall shave their heads on the day of their purification, that is, on the seventh day. 10 On the eighth day they shall bring two turtledoves or two pigeons to the priest at the entrance of the tent of meeting. 11 The priest shall offer up the one as a purification offering and the other as a burnt offering, thus making atonement for them for the sin they committed with respect to the corpse. On the same day they shall reconsecrate their heads 12 and rededicate themselves to the Lord for the period of their dedication, bringing a yearling lamb as a reparation offering. The previous period is not valid, because they defiled their dedicated heads.
