The Torah in Parashat Naso (Bamidbar 6:3-4) issues a number of prohibitions that apply to a Nazir – a person who took the nazirite vow, to abstain from certain forms of enjoyment, which include wine. The first of these commands is the prohibition against drinking wine, including vinegar made from wine, and water in which grapes had been soaked. The second command is the prohibition against eating a grape, even the peels. The Gemara understands that this prohibition includes “Boser” – grapes that have yet to fully ripen. The third command is a prohibition against “dry grapes,” referring to raisins. One might have assumed that once a grape has been dried, it is no longer considered a grape, and it should thus be permissible for a Nazir, and so the Torah added a separate prohibition forbidding a Nazir from eating raisins. The final command in this group of prohibitions is that a Nazir may not eat the pits of grapes. These commands apply to both men and women, and in all times and places. If a person who took the Nazirite vow drank a Rebi’it of wine, or ate a Ke’zayit of grapes, then he has transgressed a Torah prohibition and is liable to Malkut. All parts of the grape – the fruit itself, the pits and the peels – combine to constitute a Ke’zayit. Thus, if a Nazir ate small amounts of different portions, which altogether amount to a Ke’zayit, he is liable to Malkut.
