Reference for Nazir 4:7
הָאִישׁ מְגַלֵּחַ עַל נְזִירוּת אָבִיו וְאֵין הָאִשָּׁה מְגַלַּחַת עַל נְזִירוּת אָבִיהָ. כֵּיצַד. מִי שֶׁהָיָה אָבִיו נָזִיר וְהִפְרִישׁ מָעוֹת סְתוּמִים עַל נְזִירוּתוֹ וּמֵת, וְאָמַר הֲרֵינִי נָזִיר עַל מְנָת שֶׁאֲגַלַּח עַל מְעוֹת אַבָּא, אָמַר רַבִּי יוֹסֵי, הֲרֵי אֵלּוּ יִפְּלוּ לִנְדָבָה, אֵין זֶה מְגַלֵּחַ עַל נְזִירוּת אָבִיו. אֵיזֶהוּ שֶׁמְּגַלֵּחַ עַל נְזִירוּת אָבִיו, מִי שֶׁהָיָה הוּא וְאָבִיו נְזִירִים וְהִפְרִישׁ אָבִיו מָעוֹת סְתוּמִים לִנְזִירוּתוֹ וּמֵת, זֶהוּ שֶׁמְּגַלֵּחַ עַל נְזִירוּת אָבִיו:
A man may shave over the Naziritism of his father, but a woman may not shave over the Naziritism of her father [even if she is an inheriting daughter. We have this halachah through the kabbalah. How so? If one's father were a Nazirite, and he separated unspecified monies for his Naziritism and died, and he (the son) said: "I shall be a Nazirite on condition that I shave over (i.e., using) the monies of my father" (for the offerings). R. Yossi said: They "fall" as a gift-offering. This is not "shaving over the Naziritism of his father." What is "shaving over the Naziritism of his father"? If he and his father were Nazirites, and his father separated unspecified monies for his Naziritism, and he died — this is "shaving over the Naziritism of his father." [The halachah is not in accordance with R. Yossi, but whether his father died, and he said: "I shall be a Nazirite on condition that I shave over the monies of my father," or he and his father were Nazirites and his father died, he shaves over the Naziritism of his father. And if there were many sons, and one were beforehand and shaved over the Naziritism of his father, he acquires (the monies for his Naziritism)].
