Numbers 6:3-5

New King James Version

^3 (A)he shall separate himself from wine and similar drink; he shall drink neither vinegar made from wine nor vinegar made from similar drink; neither shall he drink any grape juice, nor eat fresh grapes or raisins. ⁴ All the days of his ^[a]separation he shall eat nothing that is produced by the grapevine, from seed to skin.

⁵ ‘All the days of the vow of his separation no ^(B)razor shall come upon his head; until the days are fulfilled for which he separated himself to the Lord, he shall be holy. Then he shall let the locks of the hair of his head grow.
