Jerusalem Talmud Nazir 3:4

משנה: הֲרֵינִי נָזִיר מֵאָה יוֹם נִיטְמָא יוֹם מֵאָה סָתַר אֶת הַכֹּל וְרִבִּי אֱלִיעֶזֶר אוֹמֵר לֹא סָתַר אֶלָּא שְׁלֹשִׁים. נִיטְמָא יוֹם מֵאָה וְאֶחָד סָתַר שְׁלֹשִׁים יוֹם. רִבִּי אֱלִיעֶזֶר אוֹמֵר לֹא סָתַר אֶלָּא שִׁבְעָה. MISHNAH: “I am a nazir for 100 days,” if he became impure on day 100 he invalidated everything but Rebbi Eliezer said, he invalidated only 30⁴⁹And the implicit vow of a nazir run for 30 days.. If he became impure on day 101, he invalidated 30; Rebbi Eliezer said, he invalidated only seven⁴¹Since he could have brought the sacrifices on the 30th day, he has to wait 7 days to cleanse himself from the impurity of the dead, shave, bring the sacrifices prescribed for the impure nazir, wait another 7 days to have some hair to shave, and then brings his 3 sacrifices and shaves in purity..

HALAKHAH: ““I am a nazir for 100 days,” etc. Rebbi Ze‘ira in the name of Rebbi Simeon ben Laqish: The reason of Rebbi Eliezer: “This is the teaching for the nazir on the day of his fulfilling;⁴⁸Then his days were not yet completed when he became impure.” if he becomes impure on the day of his fulfilling, one gives him the teaching for the nazir⁴⁹And the implicit vow of a nazir run for 30 days.. Samuel bar Abba asked before Rebbi Ze‘ira: If he becomes impure in those days⁵⁰If he became impure on the last day of his nezirut; according to R. Eliezer, how many days does he lose if he becomes impure again while keeping the 30 days of nezirut., what is their status, to be given the teaching for the nazir? Rebbi Shammai said, he is obligated by the teaching for the nazir if he becomes impure on the day of his fulfilling, and for one who becomes impure on the day of his fulfilling the seventh day is not counted⁵¹The problem arises only if he becomes impure on the 30^th day since before it is obvious that he has to start anew. If he is considered to have finished his nezirut, then the 7^th day of purification can also be the day he brings his sacrifices since “part of the day is counted as an entire day” (Nazir 2:10:2" href="/Jerusalem_Talmud_Nazir.2.10.2">Halakhah 2:10, Note 129). But if he is under the rules of the nazir who shaves on the 7^th but brings his sacrifice only on the 8^th (Numbers.6.9">Num. 6:9,Numbers.6.10">10), the 7^th day obviously cannot be the day on which he can conclude his nezirut.. Rebbi Mana asked: If he becomes impure at fulfilling, why should he invalidate 30, should he not invalidate only seven⁵²Since the entire argument follows R. Eliezer, why does he make a difference between the cases of Nazir 3:3:1" href="/Jerusalem_Talmud_Nazir.3.3.1">Mishnaiot 3 and 4?? But if somebody became impure after fulfilling⁵³If he becomes impure on day 101, R. Eliezer will apply his ruling of Nazir 3:3:1" href="/Jerusalem_Talmud_Nazir.3.3.1">Mishnah 3., the seventh day is counted for him.
