Jerusalem Talmud Nazir 3:6

משנה: מִי שֶׁנָּזַר נְזִירוּת הַרְבֶּה הִשְׁלִים נְזִירוּתוֹ וְאַחַר כָּךְ בָּא לָאָרֶץ בֵּית שַׁמַּאי אוֹמְרִים נָזִיר שְׁלֹשִׁים יוֹם. וּבֵית הִלֵּל אוֹמְרִים נָזִיר בַּתְּחִילָּה. מַעֲשֶׂה בְּהֵילֶנֵי הַמַּלְכָּה שֶׁהָלַךְ בְּנָהּ לַמִּלְחָמָה וְאָֽמְרָה אִם יָבֹא בְנִי מִן הַמִּלְחָמָה אֱהֵא נְזִירָה שֶׁבַע שָׁנִים וּבָא בְנָהּ מִן הַמִּלְחָמָה וְהָֽיְתָה נְזִירָה שֶׁבַע שָׁנִים. וּבְסוֹף שֶׁבַע שָׁנִים עָלָת לָאָרֶץ וְהוֹרוּהָ בֵית הִלֵּל שֶׁתְּהֵא נְזִירָה עוֹד שֶׁבַע שָׁנִים אֲחֵרוֹת. וּבְסוֹף שֶׁבַע שָׁנִים נִיטְמֵאת וְנִמְצֵאת נְזִירָה עֶשְׂרִים וְאַחַת שָׁנָה. אָמַר רִבִּי יְהוּדָה לֹא הָֽיְתָה נְזִירָה אֶלָּא אַרְבַּע עֶשְׂרֵה שָׁנָה. MISHNAH: If somebody vowed¹⁰²Somewhere in the diaspora. Then he should have come to the Land immediately since outside he is automatically impure in the impurity of "the land of the Gentiles" which has aspects of the impurity of corpses. a lengthy nezirut, finished his nezirut, and then came to the Land, the House of Shammai say, he is a nazir for 30 days¹⁰³The minimum needed for nezirut in genuine purity which permits the nazir to offer his sacrifices., but the House of Hillel say, he is a nazir from the start. It happened to Queen Helena¹⁰⁴Of Adiabene. that her son went to war and she said, if my son returns from the war, I shall be a nezirah for seven years. Her son returned from war and she was a nezirah for seven years. At the end of seven years, she came to the Land¹⁰⁵According to Josephus, she arrived about 43 C.E., and the House of Hillel instructed her to be a nezirah for another seven years. At the end of seven years she became impure and was nezirah for a total of 21 years. Rebbi Jehudah said, she was a nezirah only for fourteen years¹⁰⁶Since R. Ilai, R. Jehudah’s father, was a student of R. Eliezer who followed the House of Shammai, R. Jehudah tells us that Helene followed the House of Shammai, became impure at the end of 30 days, and had to restart her original nezirut..

הלכה: מִי שֶׁנָּזַר וכו׳. רִבִּי יוֹסֵי בֵּירִבִּי בּוּן אָמַר. אִיתְפַּלְּגוּן רִבִּי חִייָה בַּר יוֹסֵף וְרִבִּי יוֹחָנָן. חַד אָמַר. רִבִּי יוּדָה כְבֵית שַׁמַּי. וֶחָרָנָה אָמַר. סָבַר רִבִּי יוּדָה. שֶׁלֹּא נִטְמְאָה כָּל־עִיקָּר. אִין תֵּימַר. רִבִּי יוּדָה כְבֵית שַׁמַּי. וְתַנֵּי ל̇ יוֹם ויֹדֹ שָׁנָה. לָא תַנִּינָן מַתְנֵי חֳדָשִׁים גַּבֵּי שָׁנִים. HALAKHAH: “If somebody vowed,” etc. Rebbi Yose ben Rebbi Abun said, Rebbi Ḥiyya bar Joseph and Rebbi Joḥanan disagreed. One said, Rebbi Jehudah follows the House of Shammai. But the other said, Rebbi Jehudah thinks that she never became impure. If you say, Rebbi Jehudah follows the House of Shammai, should he not have stated 30 days and forteen years? One does not state months while reporting years¹⁰⁷The Nazir.20a">Babli disagrees, 20a..
