Numbers 6:3-5

Darby Translation

³ he shall separate himself from wine and strong drink: he shall drink no vinegar of wine, nor vinegar of strong drink, neither shall he drink any liquor of grapes, nor eat grapes, fresh or dried.

⁴ All the days of his separation shall he eat nothing that is made of the vine, from the seed-stones, even to the skin.

⁵ All the days of the vow of his separation there shall no razor come upon his head; until the days be fulfilled, that he hath consecrated himself to Jehovah, he shall be holy; he shall let the locks of the hair of his head grow.
