Numbers 6:1-4

GOD spoke to Moses: “Speak to the People of Israel; tell them, If any of you, man or woman, wants to make a special Nazirite vow, consecrating yourself totally to GOD, you must not drink any wine or beer, no intoxicating drink of any kind, not even the juice of grapes—in fact, you must not even eat grapes or raisins. For the duration of the consecration, nothing from the grapevine—not even the seeds, not even the skin—may be eaten.
