Talmud sur Oholot 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:
Ce qui suit impurifie en touchant et en portant, mais pas en ombrageant: des os de la grosseur d'un grain d'orge, [de la terre] de terres étrangères, un Beit Pras [un champ dans lequel une tombe a été labourée], un membre d'un cadavre ou un membre d'une personne vivante qui n'a pas de chair comme il convient, la colonne vertébrale ou le crâne qui sont déficients. Combien coûte une carence dans la colonne vertébrale? Les Beit Shammai disent deux vertèbres. Beit Hillel dit même une vertèbre. Et dans le crâne? Beit Shammai dit [de la taille] d'un trou [fait] par une perceuse, mais Beit Hillel dit autant que s'il avait été pris à une personne vivante, il mourrait. De quel exercice parlaient-ils? Du petit médecin, ce sont les paroles du rabbin Meir. Les Sages disent, la grande de la chambre du Temple.
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.
