He must not eat raisins

Faith – אֱמוּנָה

• Rambam (Hilchot Nezirut 5:1) includes raisins as part of the Nazir’s restrictions. Faith is shown by obeying Hashem’s word even in details that seem minor, trusting the Divine wisdom behind them.

Reverence – יִרְאַת שָׁמַיִם

• Sefer HaChinuch (Mitzvah 370) teaches that abstaining from raisins, like other grape products, cultivates reverence. By avoiding even less intoxicating forms, the Nazir reinforces awe for the boundaries Hashem set.

Holiness – קְדֻשָּׁה

• Talmud (Nazir 34b) emphasizes that the Nazir’s kedushah is comprehensive, covering wine, grapes, and raisins alike. This teaches that holiness requires consistency across all areas of life.

Nazir – נָזִיר

• Rambam describes raisins as part of the Nazir’s identity of abstinence. His lifestyle is not partial but total, marking him as wholly consecrated.

Kashrut – כַּשְׁרוּת

• Raisins are normally kosher and permissible, but for the Nazir they become forbidden. This shows how kedushah can elevate dietary law, restricting even foods that are otherwise pure.

Speech – דָּבָר

• The Nazir’s abstinence from raisins, like all his restrictions, flows from his words of vow. The mitzvah highlights how speech sanctifies ordinary foods by binding them with prohibition.

Vows / Oaths – נְדָרִים / שְׁבוּעוֹת

• Sefer HaChinuch notes that this mitzvah illustrates the far-reaching power of vows: a Nazir’s spoken declaration creates halachic boundaries that extend to every form of grapes.

Community – קְהִלָּה

• Rashi (Numbers 6:4) explains that the prohibition covers all grape products, including raisins. This makes the Nazir’s separation visible in daily communal eating, reminding others of his special status.

Bein Adam L’Makom (between a person and G-d)

• The mitzvah is a direct expression of separation to Hashem. By refraining even from dried grapes, the Nazir shows that his consecration to G-d is complete and uncompromising.
