Numbers 6:3-5

Good News Translation

^3 (A)shall abstain from wine and beer. You shall not drink any kind of drink made from grapes or eat any grapes or raisins. ⁴ As long as you are a nazirite, you shall not eat anything that comes from a grapevine, not even the seeds or skins of grapes.

⁵ As long as you are under the nazirite vow, you must not cut your hair or shave. You are bound by the vow for the full time that you are dedicated to the Lord, and you shall let your hair grow.
