וְאֵינוֹ סוֹתֵר אֶת הַקּוֹדְמִים וּמַתְחִיל וּמוֹנֶה מִיָּד וְקׇרְבָּן אֵין לוֹ בֶּאֱמֶת אָמְרוּ יְמֵי הַזָּב וְהַזָּבָה וִימֵי הֶסְגֵּרוֹ שֶׁל מְצוֹרָע הֲרֵי אֵלּוּ עוֹלִין לוֹ: and he does not negate the earlier days of his naziriteship, but they are considered part of his naziriteship term. And he starts counting the rest of his naziriteship to complete his term immediately after his purification, and he has no obligation to sacrifice an offering of impurity for these sources of ritual impurity. Actually they said an ancient tradition that these days of the impurity of the zav (Leviticus 15:1–15) and the zava (Leviticus 15:25–30) and the days of the confinement of a leper before he is confirmed as a full-fledged leper (Leviticus 13:4–5) count for him toward the period of his naziriteship.
גְּמָ׳ וְאֵלּוּ הֵן הַסְּכָכוֹת אִילָן הַמֵּיסֵךְ עַל הָאָרֶץ וּפְרָעוֹת הַיּוֹצְאוֹת מִן הַגָּדֵר: GEMARA: The Gemara explains the terms hangings and projections by citing a mishna (Oholot 8:2). And these are the hangings: A tree that overhangs the earth. And the projections are stones that protrude from a fence.
וְאֶרֶץ הָעַמִּים אִיבַּעְיָא לְהוּ אֶרֶץ הָעַמִּים מִשּׁוּם אַוֵּירָא גָּזְרוּ עָלֶיהָ אוֹ דִילְמָא מִשּׁוּם גּוּשָּׁא גָּזְרוּ עָלֶיהָ § The mishna further taught: And the land of the nations does not render a nazirite obligated to shave, despite the fact that it is considered ritually impure. The Gemara inquires with regard to the nature of this impurity. A dilemma was raised before the Sages: Did the Sages decree the land of the nations impure with regard to the air, i.e., is one rendered impure merely by being there? Or perhaps they decreed it impure with regard to the earth, i.e., one who touches the ground or overlays it becomes impure.
תָּא שְׁמַע וּמַזֶּה בַּשְּׁלִישִׁי וּבַשְּׁבִיעִי וְאִי אָמְרַתְּ מִשּׁוּם אַוֵּירָא הַזָּאָה לְמָה לִי The Gemara suggests: Come and hear a resolution to this question from the mishna, which lists one who enters the land of the nations and states: And one sprinkles on him on the third and on the seventh days. And if you say that the decree was with regard to the air, why do I need this sprinkling? He neither touched something ritually impure nor overlaid it.
אֶלָּא לָאו מִשּׁוּם גּוּשָּׁא לָא לְעוֹלָם אֵימָא לָךְ מִשּׁוּם אַוֵּירָא וְכִי קָתָנֵי אַשְּׁאָרָא Rather, is it not with regard to the earth that the land of the nations was decreed impure? The Gemara rejects this proof: No, actually I could say to you that the decree is due to the air, and when the mishna teaches that he receives the sprinkling, it is referring to the other items listed in the mishna, e.g., the grave cover, the grave walls, and a quarter-log of blood.
הָכִי נָמֵי מִסְתַּבְּרָא מִדְּקָתָנֵי וְכֵלִים הַנּוֹגְעִים בְּמֵת הָנֵי כֵּלִים בְּנֵי הַזָּאָה אִינּוּן אֶלָּא שְׁמַע מִינַּהּ אַשְּׁאָרָא The Gemara comments: So too, it is reasonable that this is the case, from the fact that the mishna also teaches: And vessels that are touching a corpse. Now do people who touch these vessels require sprinkling? Does one who touches a vessel that is ritually impure from a corpse require the sprinkling of purification water? This individual is impure only until that evening. Rather, learn from this that the halakha that he is sprinkled on the third and on the seventh days does not refer to all the cases in the mishna but only to some of the others.
