וְכִבֶּס֩ הַמִּטַּהֵ֨ר אֶת־בְּגָדָ֜יו וְגִלַּ֣ח אֶת־כָּל־שְׂעָר֗וֹ וְרָחַ֤ץ בַּמַּ֙יִם֙ וְטָהֵ֔ר וְאַחַ֖ר יָב֣וֹא אֶל־הַֽמַּחֲנֶ֑ה וְיָשַׁ֛ב מִח֥וּץ לְאָהֳל֖וֹ שִׁבְעַ֥ת יָמִֽים׃
And he that is to be cleansed shall wash his clothes, and shave off all his hair, and bathe himself in water, and he shall be clean; and after that he may come into the camp, but shall dwell outside his tent seven days.
Shenei Luchot HaBerit
Commandment 377 requires the Nazirite to shave his hair if he has defiled himself during the period of his vow, or to shave his hair at the termination of his state of נזירות (based on Leviticus. 14,8, he must shave all his hair). [This quote seems inappropriate as it deals with the מצרע, not the נזיר. Ed.]
