Numbers 6:3-5

Common English Bible

³ that person must refrain from wine and brandy. He or she may not drink wine vinegar or brandy vinegar, nor drink any grape juice or eat grapes, whether fresh or dried. ⁴ While a nazirite, the person may not eat anything produced from the grapevine, not even its seeds or skin.

⁵ For the term of the nazirite promise, no razor may be used on the head until the period of dedication to the Lord is fulfilled. The person is to be holy, letting his or her hair grow untrimmed.
