He must shave after bringing sacrifices upon completion of his Nazirite period

Faith – אֱמוּנָה

• Rambam (Hilchot Nezirut 8:1) teaches that shaving at the end of Nazirut is a required act of obedience. Faith is shown by completing the vow exactly as commanded, affirming that the consecration belonged to Hashem from beginning to end.

Reverence – יִרְאַת שָׁמַיִם

• Sefer HaChinuch (Mitzvah 374) explains that the shaving demonstrates awe for Hashem by visibly concluding the period of holiness. Reverence is reflected in not ending the vow casually but with a sacred ritual.

Holiness – קְדֻשָּׁה

• Talmud (Nazir 45a) links the Nazir’s hair to his state of consecration. Burning it beneath the korban shelamim elevates the physical symbol of his holiness into the Temple service itself.

Nazir – נָזִיר

• Rambam identifies the shaving as the defining ritual that completes Nazirut. Without this act, the period of consecration is not formally closed, underscoring its importance in the Nazir’s identity.

Temple – בֵּית הַמִּקְדָּשׁ

• Rashi (Numbers 6:18) comments that the Nazir must burn his hair “at the entrance of the Tent of Meeting,” connecting the personal vow to the sanctity of the Temple.

Sacrifices – קָרְבָּנוֹת

• The hair is burned under the fire of the korban shelamim, showing that the Nazir’s personal holiness is joined with the communal sacrificial service, sanctifying his abstinence.

Purity – טָהֳרָה

• By shaving off the consecrated hair, the Nazir transitions from separation back to normal life in purity. The act ensures no trace of the vow lingers improperly once the sacrifices are offered.

Speech – דָּבָר

• The Nazir’s vow, created through words, is concluded through an act — shaving — that physically seals the power of speech. This affirms that words of commitment carry lasting obligations.

Vows / Oaths – נְדָרִים / שְׁבוּעוֹת

• Sefer HaChinuch stresses that vows must be honored in their entirety. The shaving demonstrates the binding power of the Nazir’s oath, closing it through a Torah-prescribed ritual.

Community – קְהִלָּה

• The shaving was done publicly at the entrance of the Tent of Meeting. This communal aspect reminded Israel that consecration and its conclusion belong to Hashem, not to private choice.

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

• This mitzvah is fully between the Nazir and Hashem. The shaving and burning of the hair signify the sanctity of his vow as a personal offering to G-d, marking completion in direct relationship with the Divine.
