Numbers 6:4-6

New Century Version

⁴ While they are Nazirites, they must not eat anything that comes from the grapevine, even the seeds or the skin.

⁵ “‘During the time they have promised to belong to the Lord, they must not cut their hair. They must be holy until this special time is over. They must let their hair grow long. ⁶ During their special time of belonging to the Lord, Nazirites must not go near a dead body.
