Numbers 6:1-4

Then the LORD said to Moses, “Give the following instructions to the people of Israel. “If any of the people, either men or women, take the special vow of a Nazirite, setting themselves apart to the LORD in a special way, they must give up wine and other alcoholic drinks. They must not use vinegar made from wine or from other alcoholic drinks, they must not drink fresh grape juice, and they must not eat grapes or raisins. As long as they are bound by their Nazirite vow, they are not allowed to eat or drink anything that comes from a grapevine—not even the grape seeds or skins.
