Talmud sobre Keilim 18:2
מוּכְנִי שֶׁלָּהּ, בִּזְמַן שֶׁהִיא נִשְׁמֶטֶת, אֵינָהּ חִבּוּר לָהּ, וְאֵינָהּ נִמְדֶּדֶת עִמָּהּ, וְאֵינָהּ מַצֶּלֶת עִמָּהּ בְּאֹהֶל הַמֵּת, וְאֵין גּוֹרְרִין אוֹתָהּ בְּשַׁבָּת בִּזְמַן שֶׁיֶּשׁ בְּתוֹכָהּ מָעוֹת. וְאִם אֵינָהּ נִשְׁמֶטֶת, חִבּוּר לָהּ, וְנִמְדֶּדֶת עִמָּהּ, וּמַצֶּלֶת עִמָּהּ בְּאֹהֶל הַמֵּת, וְגוֹרְרִין אוֹתָהּ בְּשַׁבָּת אַף עַל פִּי שֶׁיֶּשׁ בְּתוֹכָהּ מָעוֹת. הַקִּמְרוֹן שֶׁלָּהּ, בִּזְמַן שֶׁהוּא קָבוּעַ, חִבּוּר לָהּ וְנִמְדָּד עִמָּהּ. וְאִם אֵינוֹ קָבוּעַ, אֵינוֹ חִבּוּר לָהּ וְאֵינוֹ נִמְדָּד עִמָּהּ. כֵּיצַד מוֹדְדִין אוֹתוֹ, רֹאשׁ תּוֹר. רַבִּי יְהוּדָה אוֹמֵר, אִם אֵינָהּ יְכוֹלָה לַעֲמֹד בִּפְנֵי עַצְמָהּ, טְהוֹרָה:
Su carro: si se puede resbalar, no se considera conectado, ni se incluye en su medición, ni brinda protección junto con él en la tienda de un cadáver, ni puede arrastrarse sobre Shabat cuando hay dinero en el mismo. Si no se puede quitar, se considera que está conectado, se incluye en su medida, ofrece protección junto con él en la tienda de un cadáver, y puede arrastrarse hacia Shabat incluso si contiene dinero. Su parte superior arqueada, si está fijada [a la caja], se considera conectada y se mide con ella, pero si no está fija, no está conectada y no se mide con ella. ¿Cómo se mide? Al triangular con una cuerda. El rabino Yehudah dice: si no puede sostenerse por sí mismo, es puro.
Jerusalem Talmud Shabbat
Wooden tools or vessels are impervious to impurity if either they are flat, not enclosing any volume, or are so large that they cannot be lifted empty or full. The latter is determined as a volume of 40 seah (a Roman culeus) 20 amphoras or 512 liter. For the House of Shammai, the volume enclosed has to be 40 seah, but for the House of Hillel the volume of the entire vessel is measured. If the undercarriage can be disconnected it can become impure even if the passenger compartment cannot, its volume is not added to the volume of the compartment according to the House of Hillel, and if it is under one roof with a corpse it is not considered a separate entity but part of the “tent”., if it can be separated it is not connected to it, will not be measured with it, does not protect in a tent with a corpse; one may not drag it on the Sabbath if it contains coins184Since coins are tools of trade forbidden on the Sabbath they cannot be moved; if the undercarriage was the receptacle of coins at nightfall it cannot be moved either..” And it was stated for this, if there were coins on it but they fell off, it may be dragged185For the second opinion the undercarriage becomes forbidden only if it was consciously selected as container of the coins; but according to the first opinion it should stay forbidden even if the coins fall off.. Rav Sheshet said, this is Rebbi Sineon’s since Rebbi Simeon said, “if it burned out it is permitted to move it.186There is no contradiction to R. Meїr from a Mishnah which is R. Simon’s. Babli 44b” They said, why do we not explain it according to everybody, if he forgot187Since there was no conscious selection as vessel for the coins it does not fall under any of R. Meir’s categories. But everybody agrees that coins may not be moved; therefore a container with coins cannot be moved.. You cannot do this, as we have stated there182Mishnah Kelim 18:2.: “if it cannot be separated it is connected to it, will be measured with it, does protect in a tent with a corpse; one may drag it on the Sabbath even though it contains coins188If the undercarriage is a permanent part of the carriage, the coins become insignificant; the carriage is not the container of the coins. But for R. Meїr one must assume that he prohibits moving the entire carriage with the coins..” Can you say about this, it is according to everybody, if he forgot?
