Talmud su Ohalot 2:3
אֵלּוּ מְטַמְּאִין בְּמַגָּע וּבְמַשָּׂא וְאֵינָן מְטַמְּאִין בְּאֹהֶל. עֶצֶם כַּשְּׂעֹרָה, וְאֶרֶץ הָעַמִּים, וּבֵית הַפְּרָס, אֵבָר מִן הַמֵּת, וְאֵבָר מִן הַחַי שֶׁאֵין עֲלֵיהֶן בָּשָׂר כָּרָאוּי, הַשִּׁדְרָה וְהַגֻּלְגֹּלֶת שֶׁחָסָרוּ. כַּמָּה הוּא חֶסְרוֹן בַּשִּׁדְרָה, בֵּית שַׁמַּאי אוֹמְרִים, שְׁתֵּי חֻלְיוֹת. וּבֵית הִלֵּל אוֹמְרִים, אֲפִלּוּ חֻלְיָה אֶחָת. וּבַגֻּלְגֹּלֶת, בֵּית שַׁמַּאי אוֹמְרִים, כִּמְלֹא מַקְדֵּחַ. וּבֵית הִלֵּל אוֹמְרִים, כְּדֵי שֶׁיִּנָּטֵל מִן הַחַי וְיָמוּת. בְּאֵיזֶה מַקְדֵּחַ אָמְרוּ, בַּקָּטָן שֶׁל רוֹפְאִים, דִּבְרֵי רַבִּי מֵאִיר. וַחֲכָמִים אוֹמְרִים, בַּגָּדוֹל שֶׁל לִשְׁכָּה:
Quanto segue si impurifica toccando e portando, ma non attraverso l'ombra: osso delle dimensioni di un granello di orzo, [terra di] terre straniere, un Beit Pras [un campo in cui è stata arata una tomba], un arto di un cadavere o un arto di una persona vivente che non ha carne come è appropriato, la colonna vertebrale o il cranio che sono carenti. Quanto è un deficit nella colonna vertebrale? Il Beit Shammai dice due vertebre. Beit Hillel dice anche una sola vertebra. E nel cranio? Beit Shammai dice [la dimensione di] un buco [fatto] da un trapano, ma Beit Hillel dice quanto se fosse preso da una persona vivente sarebbe morto. Di quale trapano parlavano? Del piccolo dei dottori, queste sono le parole del rabbino Meir. I saggi dicono, quello grande della camera del tempio.
Jerusalem Talmud Nazir
It is stated in Mishnah 9:3 that a person who finds an unattended corpse must bury it together with all surrounding earth which might have soaked up his blood. This is now qualified to apply only to complete corpses.
If one finds three graves next to one another they form a cemetery which may not be disturbed. The rules governing possible removal of graves are detailed in Halakhah 9:3. The rules arc restricted here to graves containing complete corpses.. Rebbi Joḥanan asked, how much must be missing that it have no “decay”? Might it follow what we have stated there123Mishnah Ahilut 2:3. In the list of body parts of a corpse which cause impurity by touch and carrying but not in a “tent” appears an incomplete skull. The skull is considered incomplete by the House of Shammai if it exhibits a hole made by a surgeon’s drill, but by the House of Hillel only if the missing piece was large enough so “that he would die if it was removed.”: “That he will die if it was removed.” Is it the same here? Think of it, if the esophagus was perforated, nothing was missing but he could not survive. You have only the following: If his foot was cut off, from below the joint there is “decay”, from above the joint there is no “decay”. If it was buried together with him, from below the joint it becomes an attachment to him, from above the joint it does not become an attachment to him.
