Numbers 6:4-6

New Revised Standard Version Catholic Edition

⁴ All their days as nazirites^[a] they shall eat nothing that is produced by the grapevine, not even the seeds or the skins.

⁵ All the days of their nazirite vow no razor shall come upon the head; until the time is completed for which they separate themselves to the Lord, they shall be holy; they shall let the locks of the head grow long.

⁶ All the days that they separate themselves to the Lord they shall not go near a corpse.
