Comentário sobre Baba Batra 5:5
הַמּוֹכֵר רֹאשׁ בְּהֵמָה גַסָּה, לֹא מָכַר אֶת הָרַגְלָיִם. מָכַר אֶת הָרַגְלַיִם, לֹא מָכַר אֶת הָרֹאשׁ. מָכַר אֶת הַקָּנֶה, לֹא מָכַר אֶת הַכָּבֵד. מָכַר אֶת הַכָּבֵד, לֹא מָכַר אֶת הַקָּנֶה. אֲבָל בְּדַקָּה, מָכַר אֶת הָרֹאשׁ, מָכַר אֶת הָרַגְלָיִם. מָכַר אֶת הָרַגְלַיִם, לֹא מָכַר אֶת הָרֹאשׁ. מָכַר אֶת הַקָּנֶה, מָכַר אֶת הַכָּבֵד. מָכַר אֶת הַכָּבֵד, לֹא מָכַר אֶת הַקָּנֶה:
Quem vende a cabeça de um animal grande não vendeu os pés. [No Tosefta, afirma-se: Onde é isso? Onde eles não estão acostumados a fazê-lo. Mas onde eles estão, "tudo está de acordo com o costume da terra".]] Se ele vendeu os pés, não vendeu a cabeça. Se ele vendeu a traquéia [ou seja, o pulmão, assim chamado por causa da traquéia], ele não vendeu o fígado. Se ele vendeu o fígado, ele não vendeu o pulmão. Mas em um animal pequeno, se ele vendeu a cabeça, ele vendeu as pernas; se ele vendeu as pernas, ele não vendeu a cabeça. Se ele vendeu a traquéia, ele vendeu o fígado; se ele vendeu o fígado, ele não vendeu a traquéia.
Bartenura on Mishnah Bava Batra
English Explanation of Mishnah Bava Batra
But in the case of a small animal: If he sold the head he has sold the feet. If he sold the feet he has not sold the head. If he sold the lungs he has sold the liver. If he sold the liver he has not sold the lungs.
Mishnah five deals with what is included in the sale of large and small animals.
This mishnah draws a distinction between large animals, such as cows, and small animals such as sheep or goats. In section one we learn that each part of a large animal is significant enough to be sold separately. In other words, if one sells one part of a large animal, he has not necessarily sold another part of the animal with it. However, with small animals some parts are sold with others and some parts are sold alone. For instance, if one bought the head, the feet are automatically included. Likewise if one bought the lungs, the liver is automatically included. However, the opposites are not true. If one bought the feet he has not automatically bought the head. If one bought the liver he has not automatically bought the lungs.
