Numbers 6:4-6

Darby Translation

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.

⁶ All the days that he hath consecrated himself to Jehovah, he shall come near no dead body.
