Numbers 6:5-7

Common English Bible

⁵ For the term of the nazirite promise, no razor may be used on the head until the period of dedication to the Lord is fulfilled. The person is to be holy, letting his or her hair grow untrimmed. ⁶ The period of dedication to the Lord also requires that the person not go near a corpse, ⁷ whether father, mother, brother, or sister. Nazirites should not defile themselves because of the death of these people, because they bear the sign of their dedication to God on their heads.
