Rabba actually said that Rav Naḥman said: If one sold another a sand field and a pond, and the buyer took possession of the sand field, he has also acquired the pond. The Gemara asks: This is obvious, as Shmuel says: If one sold ten fields to another in ten different regions, once he takes possession of one of them, he has acquired them all. The Gemara explains why Rav Naḥman’s statement was nevertheless necessary: It is necessary lest you say that there, in the case of the ten fields, the land is all located in one geographic block with a single use, and therefore all the fields are acquired together. But here, in the case of the sand field and the pond, this, the sand field, has a distinct use, and that, the pond, has a distinct use, and therefore taking possession of one of them should not effect acquisition of the other. Therefore, Rav Naḥman teaches us that if the buyer took possession of the sand field, he has acquired the pond as well.

MISHNA: One who sells an olive press without specifying what is included in the sale has sold with it the yam and the memel and the betulot, the immovable elements of the olive press. But he has not sold with it the avirim and the galgal and the kora, the movable utensils of the olive press. When the seller says to the buyer: I am selling you it and everything that is in it, all these components are sold along with the olive press, even the movable utensils. Rabbi Eliezer says: One who sells an olive press has sold the kora as well, as it is the most fundamental element of the olive press.

GEMARA: The Gemara explains the terms used in the mishna. The yam is the lentil, the round stationary container into which the olives are placed before being crushed. As for the memel, Rabbi Abba bar Memel said: This is the crusher, the utensil used to pound and crush the olives. As for the betulot, Rabbi Yoḥanan said: These are the cedar posts [klonsot] that support the beam of the olive press. The avirim are the pressers, wooden boards that are placed on top of the crushed olives, and upon which the beam is lowered in order to press the olives. The galgal is the ḥumrata, a round stone that is placed on the beam to weigh it down. The kora is the heavy wooden beam used to press down upon the olives and thereby extract the oil.

The Sages taught in a baraita (Tosefta, 3:2): One who sells an olive press without specifying what is included in the sale has sold with it the boards that are fixed in place to hold the olives; and the vats for collecting the oil, and the crushers, used to pound and crush the olives before pressing them, and the lower millstone, i.e., the stationary millstone base; but not the upper millstone. But when the seller says to the buyer: I am selling you it and everything that is in it, all these components are sold. Both in this case, where he executes the sale without specification, and in that case, where he adds the phrase that he is selling everything that is in the olive press, he has not sold the wooden boards that are placed on top of the crushed olives when they are being pressed, nor has he sold the sacks, nor has he sold the leather bags for carrying the olives, as these are all movable goods that are not specifically part of the olive press.

Rabbi Eliezer says: One who sells an olive press has sold the heavy wooden beam used to press down upon the olives, as it is called an olive press [beit habad] only due to this beam, the most essential part of the press, and this beam is otherwise known as a bad.

MISHNA: One who sells a bathhouse without specifying what is included in the sale has not sold with it the boards that are placed on the floor, nor has he sold the basins or the curtains [habilaniyot]. When the seller says to the buyer: I am selling you it and everything that is in it, all these components are sold along with the bathhouse. Both in this case, where he executes the sale without specification, and in that case, where he adds the phrase that he is selling everything that is in the bathhouse, he has not sold the tanks of water, nor has he sold the storerooms for wood, as an explicit sales agreement is required for these matters.

GEMARA: The Sages taught in a baraita (Tosefta, 3:3): One who sells a bathhouse without specifying what is included in the sale has sold with it the storeroom for the boards, and the storeroom for the implements called yekamin, and the storeroom for the basins, and the storeroom for the curtains [vilaot], but he has not sold the boards themselves, nor the yekamin themselves, nor the basins themselves, nor the curtains themselves. When the seller says to the buyer: I am selling you it and everything that is in it, all these components are sold along with the bathhouse. Both in this case, where he executes the sale without specification, and in that case, where he adds the phrase that he is selling everything that is in the bathhouse, he has not sold him the pools that supply him with water, whether
