Numbers 6:3-5

Young's Literal Translation

³ from wine and strong drink he doth keep separate; vinegar of wine, and vinegar of strong drink he doth not drink, and any juice of grapes he doth not drink, and grapes moist or dry he doth not eat;

⁴ all days of his separation, of anything which is made of the wine-vine, from kernels even unto husk, he doth not eat.

⁵ `All days of the vow of his separation a razor doth not pass over his head; till the fulness of the days which he doth separate to Jehovah he is holy; grown up hath the upper part of the hair of his head.
