Numbers 6:6-8

New Revised Standard Version, Anglicised

⁶ All the days that they separate themselves to the Lord they shall not go near a corpse. ⁷ Even if their father or mother, brother or sister, should die, they may not defile themselves; because their consecration to God is upon the head. ⁸ All their days as nazirites^[a] they are holy to the Lord.
