Talmud for Bava Batra 5:1
הַמּוֹכֵר אֶת הַסְּפִינָה, מָכַר אֶת הַתֹּרֶן וְאֶת הַנֵּס וְאֶת הָעוֹגִין וְאֶת כָּל הַמַּנְהִיגִין אוֹתָהּ, אֲבָל לֹא מָכַר לֹא אֶת הָעֲבָדִים, וְלֹא אֶת הַמַּרְצוּפִין, וְלֹא אֶת הָאַנְתִּיקִי. וּבִזְמַן שֶׁאָמַר לוֹ הִיא וְכָל מַה שֶּׁבְּתוֹכָהּ, הֲרֵי כֻלָּן מְכוּרִין. מָכַר אֶת הַקָּרוֹן, לֹא מָכַר אֶת הַפְּרָדוֹת. מָכַר אֶת הַפְּרָדוֹת, לֹא מָכַר אֶת הַקָּרוֹן. מָכַר אֶת הַצֶּמֶד, לֹא מָכַר אֶת הַבָּקָר. מָכַר אֶת הַבָּקָר, לֹא מָכַר אֶת הַצֶּמֶד. רַבִּי יְהוּדָה אוֹמֵר, הַדָּמִים מוֹדִיעִין. כֵּיצַד, אָמַר לוֹ מְכוֹר לִי צִמְדְּךָ בְּמָאתַיִם זוּז, הַדָּבָר יָדוּעַ שֶׁאֵין הַצֶּמֶד בְּמָאתַיִם זוּז. וַחֲכָמִים אוֹמְרִים, אֵין הַדָּמִים רְאָיָה:
One who sells a boat has sold the mast, the sail, the anchor, and all of its "conductors" [the oars, by which the boat is "conducted" to its destination]. But he has not sold the sailors, the packing bags [for its cargo], or its wares. [And all those things mentioned below under "If he sold … he has not sold …" — if he made a gift of the boat or dedicated it, they are not included in the gift or the dedication. They are not like bor, duth, or wine vat (above), which are all "ground-fixed" and "absorbed" in the field relative to dedication and gift, but these are not "absorbed" at all.] And if he said: "It and all that is in it," all are sold. If he sold the wagon, he has not sold the p'radoth [the animals pulling the wagon. This, if they are not attached to it at the time of the sale. Some understand "p'radoth" as the wood pieces, separate (nifradim) from the wagon, by which the wagon is pulled. This, if they are not tied to it at the time of the sale.] If he sold the p'radoth, he has not sold the wagon. If he sold the yoke, he has not sold the team. If he sold the team, he has not sold the yoke. R. Yehudah says: The money apprises us (as to what has been sold.) How so? If he said to him: "Sell me your yoke for two hundred zuz," it is obvious that a yoke (itself) is not sold for two hundred zuz. The sages say: The money is no proof. [As to the ruling (Bava Metzia 4:3) that (with an overcharge of) a sixth the sale is valid and the overcharge is returned, and with an overcharge of more than a sixth the sale is annulled, this is when the buyer might mistakenly think that it is worth that much (more than a sixth, etc.), so that the sale is "a sale in error." But where the buyer would not make such a mistake, as in buying a yoke worth a zuz for two hundred, we say that he gave it to him as a gift and the sale is not annulled. The halachah is not in accordance with R. Yehudah.]
