We begin our study with a discussion from the Mishnah concerning the sale of items to a non-Jew. The Mishnah states that one may not sell anything attached to the ground to a non-Jew. However, once an item is detached, it may be sold. Rabbi Yehudah offers a more lenient view, permitting the sale of an attached item if there is an explicit intention for it to be detached. The Tanna Kamma, the anonymous first opinion, disputes this, maintaining that only items already detached may be sold. This forms the core dispute between the Tanna Kamma and Rabbi Yehudah.
The Gemara illustrates this dispute through three distinct cases. The first case involves a tree: Rabbi Yehudah permits selling a tree still rooted in the ground, provided the condition is made that it will be cut. The Tanna Kamma, however, requires the tree to be cut first. The second case concerns stubble or grass, referred to as shachat. Again, Rabbi Yehudah allows its sale while attached, on the condition that it will be cut, whereas the Tanna Kamma insists it must be cut beforehand. The third case involves stalks of wheat, or kama, presenting the same disagreement. The Gemara then questions why all three cases are necessary to illustrate this single dispute.
The Gemara explains the necessity of all three cases by highlighting subtle distinctions. If only the case of a tree had been presented, one might assume that the Tanna Kamma's strictness applies specifically to a tree because leaving it in the ground causes no loss; a tree naturally belongs in the ground. Thus, the Tanna Kamma might suspect the non-Jew would not fulfill the condition to cut it, as there's no inherent disadvantage in leaving it. However, for items like shachat and kama, which spoil or decay if left in the ground, one might think even the Tanna Kamma would agree with Rabbi Yehudah, allowing their sale while attached, assuming the non-Jew would certainly cut them to prevent spoilage. Therefore, the Mishnah needs to teach us that even in these cases, the Tanna Kamma maintains his position: only detached items may be sold.
Conversely, if only the cases of shachat and kama had been presented, one might think Rabbi Yehudah's leniency applies only to them. These items, when left in the ground, do not show a noticeable enhancement (shevach) over time, or their enhancement is minimal and quickly turns to spoilage. Thus, the non-Jew would have no incentive to leave them in the ground, making Rabbi Yehudah comfortable trusting the condition. However, a tree, if left in the ground, continues to grow and enhance its value. One might then assume that Rabbi Yehudah would be strict regarding a tree, fearing the non-Jew might leave it to grow, thereby violating the spirit of the sale. The Mishnah, by including all three, teaches that Rabbi Yehudah's leniency applies across the board: he trusts the non-Jew to fulfill the condition of detachment in all these scenarios. Conversely, the Tanna Kamma's stringency also applies to all three, requiring prior detachment due to the concern of the non-Jew leaving the item attached to the ground, which is akin to selling land.
Rashi elaborates on the concern regarding shachat, explaining that if the stubble is left in the ground, it constitutes giving the non-Jew a piece of land (karka), which is forbidden due to the prohibition of "You shall not grant them favor" (Lo Titen Lahem Chen). Rashi further clarifies the Gemara's distinction regarding enhancement: kama and trees have marginal or unnoticeable enhancement if left in the ground, making it likely the non-Jew will cut them. However, shachat, being young stubble, shows noticeable enhancement the longer it remains in the ground. One might have thought that even Rabbi Yehudah would agree to prohibit selling shachat while attached, due to the concern that the non-Jew would leave it to grow. The Mishnah teaches that Rabbi Yehudah still permits it, provided the stipulation is made.
The Gemara then transitions to a related but distinct halachic question, comparing it to the previous dispute. Earlier in the tractate, we learned that it is forbidden to sell a large animal (behema gasa) to a non-Jew. Two reasons were given: first, selling might lead to renting, and renting might lead to the animal working on Shabbat, which is forbidden. Second, one might sell the animal on the eve of Shabbat, and the non-Jew, wishing to test it, would load it and command it to move, causing the Jew to violate Shabbat through the animal's labor. The question now arises: if one sells an animal to a non-Jew with the explicit intention for it to be slaughtered (al menat lishchot), does this condition alleviate the concern? We compare this to the dispute regarding land-attached items: just as Rabbi Yehudah permits selling an attached item with a condition, would he also permit selling an animal with a condition to slaughter it?
A potential distinction is raised: when selling a tree, it remains on the Jew's land, allowing the Jew some control over the non-Jew's actions. The non-Jew cannot simply leave the tree in the ground indefinitely because it is not his land. However, once an animal is sold to a non-Jew, even with a stipulation, the Jew loses all control. The non-Jew might simply ignore the condition. The Gemara responds by citing a Baraisa: "One may sell an animal with the condition to slaughter it, and he slaughters it." Rabbi Yehudah maintains his position, allowing the sale with the stipulation. The Tanna Kamma, however, insists that only an animal already slaughtered may be sold. Thus, the same dispute between the Tanna Kamma and Rabbi Yehudah concerning land-attached items also applies to the sale of animals.
The Mishnah then introduces a new topic: "One may not rent houses to them in Eretz Yisrael." This prohibition is a rabbinic decree (gezeirah). The underlying concern is that renting might lead to selling, and selling land in Eretz Yisrael to a non-Jew is a Torah prohibition (issur de'Oraita). The Mishnah adds, "and certainly not fields," implying fields are even more problematic. The Gemara will later explain that fields have two prohibitions associated with them, making them stricter. The Mishnah's language thus establishes a hierarchy of stringency: fields are more severe than houses.
Next, the Mishnah discusses the halachic status of Syria (Aram Soba), which was conquered by King David. While it has some sanctity (Kedushah), its status is debated. In Syria, one may rent houses to non-Jews, but not fields. Rashi explains that in Syria, the Sages did not enact a decree against renting houses due to the concern of selling. This is because even if one were to sell land in Syria, it would not be a Torah prohibition, as the prohibition of "You shall not grant them favor" applies specifically to Eretz Yisrael. Selling in Syria is a rabbinic prohibition, but renting is permitted. However, fields in Syria remain prohibited for rent, due to the two prohibitions associated with them. This means that while renting houses in Syria is permitted, renting fields is not, reflecting the greater stringency applied to fields.
Finally, the Mishnah addresses lands outside of Eretz Yisrael and Syria (Chutz La'aretz). In Chutz La'aretz, one may sell houses to non-Jews without restriction and even rent fields. This is because Chutz La'aretz is far removed, and the Sages did not enact a decree that selling or renting there might lead to selling in Eretz Yisrael. According to Rabbi Meir, if one can sell houses in Chutz La'aretz, one can certainly rent them. However, fields still carry restrictions, even in Chutz La'aretz, due to their inherent stringency.
Rabbi Yosef presents an entirely different view, significantly more lenient. He permits renting houses to non-Jews even in Eretz Yisrael. Unlike the Tanna Kamma, Rabbi Yosef does not agree that renting houses in Eretz Yisrael is prohibited due to the concern of selling. However, he agrees that renting fields in Eretz Yisrael is forbidden. In Syria, according to Rabbi Yosef, one may even sell houses to non-Jews and rent fields, essentially dropping the stringency a notch further. In Chutz La'aretz, Rabbi Yosef allows selling both houses and fields, and renting both, with no restrictions at all. Essentially, Rabbi Yosef applies the stringency of the prohibitions at a lower level across all zones.
The Gemara then clarifies a crucial point: even in cases where renting is permitted, such as houses in Syria or Chutz La'aretz, it is only for non-residential purposes. One may not rent a house to a non-Jew for dwelling, because the non-Jew might bring idolatry (Avodah Zarah) into the house, which is forbidden. Therefore, renting is restricted to purposes like a stable for animals or storage. The Mishnah also adds a general restriction: one may never rent a bathhouse to a non-Jew, regardless of location. This is due to the concern of marit ayin (appearance of wrongdoing). If a non-Jew operates a bathhouse owned by a Jew on Shabbat, and smoke is seen from the chimney, people might assume the Jew instructed the non-Jew to work on Shabbat, thereby bringing a bad name to the Jew.
The Gemara returns to the initial statement of the Mishnah: "You can't rent homes in Eretz Yisrael, and it goes without saying fields." It asks why fields are considered worse. The Gemara explains that fields have two prohibitions: first, selling a piece of Eretz Yisrael to a non-Jew. Second, by allowing a non-Jew to plant and work the field, one causes the cessation of the obligation of tithes (Ma'aserot) from the land, as non-Jews are exempt from this obligation. This is a special prohibition against uprooting the law of Ma'aserot from the land of Eretz Yisrael. Houses, however, only have the first prohibition (selling land in Eretz Yisrael). While one might argue that houses also have a second issue, the obligation of Mezuzah, the Gemara distinguishes: the obligation of Mezuzah is on the person dwelling in the house (Chovat Hadar), not inherently on the house itself. A Jew can own a house without a Mezuzah if he doesn't dwell in it. Therefore, selling a house to a non-Jew does not necessarily remove it from the obligation of Mezuzah, as it might not have been obligated in the first place. In contrast, the obligation of Ma'aserot is inherent to the produce of the field itself. Thus, fields indeed carry two prohibitions, making them stricter.
Tosafot clarifies this point, stating that since the obligation of Mezuzah is not inherent to the house, the Sages did not enact a decree against renting houses in Eretz Yisrael due to the concern of selling, because even selling only involves one prohibition. However, for fields, where selling involves two prohibitions (transferring land and nullifying Ma'aserot), the Sages were more prone to enact stricter decrees, even prohibiting renting due to the concern of selling.
The Gemara then addresses the ruling for Syria, where one may rent houses but not fields. It asks why a decree against renting houses in Syria, out of concern for selling in Eretz Yisrael, is not made. After all, selling in Syria is prohibited due to the concern of selling in Eretz Yisrael. The Gemara explains that prohibiting renting in Syria out of concern for renting in Eretz Yisrael, which is itself prohibited out of concern for selling in Eretz Yisrael, would be a "double decree" (gezeirah le'gezeirah), which the Sages generally avoid. However, for fields in Syria, renting is prohibited. This is not a double decree. The Gemara explains that Syria, having been conquered by an individual (Kibush Yachid) like King David, is considered to have some Kedushah. Therefore, selling fields in Syria is prohibited because of this Kedushah and the issue of Ma'aserot. Renting fields in Syria is then prohibited as a direct decree against selling fields in Syria (a single decree), not a double decree leading back to Eretz Yisrael. Houses in Syria, having only one prohibition (the Kedushah of the land), are treated more leniently, allowing renting.
The Gemara then discusses Chutz La'aretz according to Rabbi Meir, where one may sell houses and rent fields. The same logic applies: fields, having two prohibitions, are treated more strictly, even in Chutz La'aretz. Houses, with only one prohibition, are treated more leniently, allowing even sale.
The Gemara returns to Rabbi Yosef's view. He permits renting houses in Eretz Yisrael. His reasoning is that houses only involve one prohibition (selling land in Eretz Yisrael), and the Sages have the discretion to decide which decrees to enact. For houses, where the concern is only one prohibition, Rabbi Yosef chooses not to enact a decree against renting due to the concern of selling. However, for fields, which involve two prohibitions (selling land and nullifying Ma'aserot), he agrees to the stringency, prohibiting renting because it could lead to selling. In Syria, Rabbi Yosef permits selling houses because he considers Syria's Kedushah from Kibush Yachid to be less significant, effectively negating the prohibition of selling. He also permits renting fields in Syria. In Chutz La'aretz, Rabbi Yosef permits everything, including selling and renting both houses and fields, as there are no inherent prohibitions there.
A significant practical question arises: how do we permit renting houses to non-Jews in Chutz La'aretz today, given the Mishnah's restriction against residential rental? The Mishnah stated that even where renting is allowed, it's not for dwelling due to the concern of Avodah Zarah. Tosafot offers two explanations. First, Tosafot suggests that in contemporary times, non-Jews do not bring Avodah Zarah into their homes in a permanent, fixed manner (bikvi'ut), as they did in ancient times. Idols are only brought in occasionally, such as during a death or illness, and even then, not for worship. Therefore, modern homes are akin to stables, where Avodah Zarah is not permanently housed, thus permitting rental. Second, Rabbeinu Chaim Kohen offers a different leniency. He argues that the Mishnah's restriction against residential rental ("even in a place where one may rent, not for dwelling") applies only to places where the sole permission is for renting, but selling is prohibited. In such places, there is already a degree of stringency. However, in places like Chutz La'aretz, where selling is entirely permitted, the Sages did not impose restrictions on residential renting. The logic is that a Jew's house in Chutz La'aretz is not considered his "real house" (beitecha), which refers to his home in Eretz Yisrael. Since it's not his primary "house," the concern about Avodah Zarah is lessened. This is the primary basis upon which we rely today for renting homes to non-Jews in Chutz La'aretz.
The Gemara continues with another restriction: one may not sell three houses to three non-Jews in a row, as this would create a non-Jewish neighborhood (shechunah). This is prohibited because it could bring harm (hezek) to the Jewish residents, or cause them to stumble (lifnei iver) by making them leave the neighborhood. The Gemara asks if one may sell three houses to a single non-Jew. One might argue that this is also forbidden, as the non-Jew could then sell the other two houses to two additional non-Jews, still creating a non-Jewish neighborhood. The Gemara responds that we are only concerned with a direct stumbling block (lifnei iver), not a "stumbling block of a stumbling block" (lifnei delifnei). The immediate act of selling three houses to one non-Jew is not considered creating a non-Jewish neighborhood. We do not legislate for potential subsequent actions that are two steps removed from the original act. Therefore, selling three houses to one non-Jew is permitted, as long as it doesn't immediately create a non-Jewish neighborhood.
The Mishnah's phrase "even in a place where one may rent" implies that there are places where renting is forbidden. This statement aligns with Rabbi Meir's view, who prohibits renting in Eretz Yisrael and Syria. However, according to Rabbi Yosef, one may rent everywhere (at least for non-residential purposes). Therefore, this phrase in the Mishnah must refer to Rabbi Meir's opinion.
Finally, the Gemara reiterates the prohibition against renting a bathhouse to a non-Jew, citing Rabban Shimon Ben Gamliel. The reason is marit ayin: if a non-Jew operates a Jewish-owned bathhouse on Shabbat or Yom Tov, and people see smoke, they will assume the Jew is having the non-Jew work for him, even if the non-Jew is working for himself. The Gemara then asks about renting a bathhouse to a Samaritan (Kuti). A Kuti is not considered an idol worshipper and accepts Shabbat. Therefore, one might think it is permitted, as the Kuti would not operate it on Shabbat. However, the Gemara notes that Kutim do not accept the rabbinic prohibitions of Chol HaMoed (intermediate days of festivals). Thus, they might operate the bathhouse on Chol HaMoed. This would still lead to marit ayin, as people might assume the Jew instructed them to work. However, making a fire and boiling water on Chol HaMoed is permitted for a Jew for certain needs. Thus, the concern of marit ayin for a Kuti operating a bathhouse on Chol HaMoed is not as strong as on Shabbat. The Gemara concludes that Kutim are not a concern for marit ayin on Chol HaMoed because they do not follow rabbinic interpretations (derashot) from which these prohibitions are derived.
Returning to the discussion of selling an animal to a non-Jew, Tosafot addresses a question: earlier, it was stated that in certain cases, one can assume a non-Jew intends to slaughter a cow even without an explicit stipulation. Why then is an explicit stipulation necessary for other animals? Tosafot clarifies that the assumption of slaughter applies only to cows. For other animals, an explicit stipulation is indeed required. The ultimate halachic conclusion (Halakha) follows Rabbi Yehudah: as long as the non-Jew explicitly states the intention to slaughter the animal, the sale is permitted, just as he trusts the non-Jew to cut a tree from the ground when stipulated. Therefore, the Halakha follows Rabbi Yehudah in both cases.
