25aכ״ה א

מאן דשרי דהא ליכא דיורין ומאן דאסר זימנין דהוי בה דיורין ואתי לטלטולי

The Sage who permits doing so holds that it is permitted since in the yard itself there are no residents, and a place without residents cannot prohibit carrying in another, adjacent domain. And the Sage who prohibits doing so holds that it is prohibited because sometimes there are residents in it who can prohibit carrying in the other domain, and people might unwittingly come to carry from the yard to the town in their usual manner, even though it is prohibited.

קרפף יותר מבית סאתים שלא הוקף לדירה ובא למעטו מיעטו באילנות לא הוי מיעוט

With regard to a karpef that measures more than two beit se’a and that had not been fenced in from the outset for the purpose of residence, and one came to reduce its size, if he reduced it by planting trees in a section of the space, it is not a valid reduction, because trees are commonly found in a karpef designed for dwelling; therefore, they are not considered something out of the ordinary that would reduce its size.

בנה בו עמוד גבוה עשרה ורחב ארבעה הוי מיעוט פחות משלשה לא הוי מיעוט משלשה ועד ארבעה רבה אמר הוי מיעוט ורבא אמר לא הוי מיעוט

But if he built up a column ten handbreadths high and four handbreadths wide, it is an effective reduction, i.e., if the karpef is thereby reduced to the area of two beit se’a, one is permitted to carry within it. However, if the column is less than three handbreadths wide, it is not an effective reduction. And if it is between three to four handbreadths wide, there is a dispute between amora’im. Rabba said: It constitutes an effective reduction, and Rava said: It does not constitute an effective reduction.

רבה אמר הוי מיעוט דהא נפיק ליה מתורת לבוד רבא אמר לא הוי מיעוט כיון דלא הוי מקום ארבעה לא חשיב

The Gemara explains the two opinions. Rabba said that it constitutes an effective reduction because it is large enough to be excluded from the principle of lavud, namely, that solid surfaces with gaps between them less than three handbreadths are considered joined. Since the column stands independently, it reduces the size of the karpef. Rava said that it does constitute a valid reduction because as it is not a place of at least four handbreadths, it is not significant. An area of less than four handbreadths is not considered independent.

הרחיק מן הכותל ארבעה ועשה מחיצה הועיל פחות משלשה לא הועיל משלשה ועד ארבעה רבה אמר הועיל רבא אמר אינו מועיל

It was further stated: If one distanced himself four handbreadths from the wall of the karpef and erected an additional partition for the sake of dwelling, it is effective in permitting one to carry in the fenced-off inner area. But if the distance is less than three handbreadths, it is not effective, as the new wall is considered attached to the first by means of the principle of lavud, and it is like one partition built on top of another. And if the distance is between three to four handbreadths, that is the topic of the dispute among the amora’im, in which Rabba said: It is effective, and Rava said: It is not effective.

רבה אמר הועיל דהא נפיק ליה מתורת לבוד רבא אמר אינו מועיל כיון דלא הוי מקום ארבעה לא חשיב

The Gemara explains the two opinions. Rabba said: It is effective, as it is far enough away to be removed from the principle of lavud. Rava disagreed and said: It is not effective, because as it is not a place of at least four handbreadths, it is not significant.

רב שימי מתני לקולא טח בו טיט ויכול לעמוד בפני עצמו הוי מיעוט אינו יכול לעמוד בפני עצמו רבה אמר הוי מיעוט רבא אמר לא הוי מיעוט

Rav Simi would teach a more lenient version of the dispute between Rabba and Rava. If one plastered the walls of a karpef larger than two beit se’a with plaster, and the plaster can stand on its own, all agree that it is an effective reduction, as it is considered as if he has made a new partition. But if the plaster cannot stand on its own, and it only stays in place because it is attached to the existing wall, there is an amoraic dispute in which Rabba said: It is an effective reduction, and Rava said: It is not an effective reduction.

רבה אמר הוי מיעוט השתא מיהא קאי רבא אמר לא הוי מיעוט כיון דלא יכול למיקם בפני עצמו לא כלום הוא

The Gemara explains the two opinions. Rabba says: It is an effective reduction, because for now, in any case, it stands. Rava says: It is not an effective reduction, because as it cannot stand on its own, it is nothing, i.e., it is insignificant.

הרחיק מן התל ארבעה ועשה מחיצה הועיל

If one distanced himself four handbreadths from a mound ten handbreadths high that stands in a karpef larger than two beit se’a, and he erected a partition for the sake of dwelling, it is effective to permit one to carry.

פחות משלשה או על שפת התל רב חסדא ורב המנונא חד אמר הועיל וחד אמר לא הועיל

But if he erected the partition less than three handbreadths from the mound or on the edge of the mound itself, so that it is like a partition built on top of another partition, this is a dispute between Rav Ḥisda and Rav Hamnuna. One of them said: It is effective, and the other one said: It is not effective.

תסתיים דרב חסדא אמר הועיל דאתמר העושה מחיצה על גבי מחיצה אמר רב חסדא בשבת הועיל

The Gemara seeks to clarify which of the Sages held which opinion. Conclude that it was Rav Ḥisda who said it is effective, for it was stated that the amora’im disagreed about the following: If one erected a partition on top of an existing partition, Rav Ḥisda said: With regard to the halakhot of Shabbat, e.g., if the first partition was not erected for the purpose of residence, the second partition is effective.

בנכסי הגר לא קנה

However, with regard to the property of a convert, he does not acquire it. The property of a convert who dies without heirs is regarded as ownerless unless he had transferred it to someone as a gift during his lifetime. Whoever first implements a valid mode of acquisition upon such property acquires it. For example, one may acquire property by performing an act of taking possession, such as construction of a partition around it. But if one erects a partition around the property of a deceased convert on top of an existing partition, he does not acquire the property in this manner.

ורב ששת אמר אף בשבת נמי לא הועיל תסתיים

And Rav Sheshet said: Even with regard to Shabbat it is not effective. The Gemara comments: Indeed, conclude that it is Rav Ḥisda who maintains that one partition built on top of another is effective for Shabbat.

אמר רב חסדא ומודה לי רב ששת שאם עשה מחיצה על התל שהועיל

Rav Ḥisda said: Rav Sheshet agrees with me that if one erected a partition on the mound, rather than merely adjacent to it, that it is effective to permit one to carry on the mound itself, even though, according to him, it is prohibited to carry in the rest of the karpef.

מאי טעמא הואיל ובאויר מחיצות העליונות הוא דר

What is the reason for this? Since he dwells in the space between the upper partitions, he utilizes these new partitions and they serve a function. Although in relation to one positioned below the mound these are partitions built on top of the pre-existing partitions of the mound, and therefore they do not allow him to carry in the karpef, they are nonetheless effective in allowing him to carry on the mound itself.

בעי רבה בר בר חנה נבלעו מחיצות התחתונות והעליונות קיימות מהו

Rabba bar bar Ḥana raised a dilemma: If the lower partitions were swallowed up, e.g., if they sank in boggy ground, and the upper partitions that he had erected still stand, what is the law?

למאי אי לנכסי הגר היינו דירמיה ביראה דאמר ירמיה ביראה אמר רב יהודה האי מאן דשדא ליפתא אפילא דארעא דגר ואתא ישראל אחרינא רפק בה פורתא בתרא קני קמא לא קני

The Gemara asks: With regard to what issue was this dilemma raised? If it was raised with regard to acquiring the property of a convert, this is precisely the same as the ruling cited by Yirmeya Bira’a, as Yirmeya Bira’a said that Rav Yehuda said: If one sowed turnip seeds in cracks which he found in land that had belonged to a convert, and another Jew came and plowed the ground a little, the latter one, the one who plowed, acquires the property, and the first one does not acquire it.

מאי טעמא בעידנא דשדא לא קא שבח כי קא שבחא ממילא קא משבחא

What is the reason that the first one who sowed the seeds does not acquire the property? At the time that he sowed, the land was not improved by his sowing. When it did improve, with the growth of the turnips, it improved on its own. That is to say, the act of sowing alone is not a sufficiently noticeable action that changes and improves the property at the time. Although the sowing later proves to have been beneficial, this is seen as an improvement of the land that comes on its own. Therefore, an action that will only provide benefit in the future cannot serve as an act of acquisition.

ואלא לענין שבת הוי מחיצה הנעשה בשבת

Rather, you must say that the dilemma was raised with respect to Shabbat, in which case it is a partition that was made on Shabbat; beforehand it was not a valid partition, and the upper ones acquired the status of a partition only after the lower partitions sank into the ground.

ותניא כל מחיצה הנעשה בשבת בין בשוגג בין במזיד שמה מחיצה

And it was already taught in a baraita: Any partition made on Shabbat, whether unwittingly or intentionally, is called a valid partition. Consequently, the upper partitions should be regarded as valid partitions that allow one to carry in the karpef.

לאו איתמר עלה אמר רב נחמן לא שנו אלא לזרוק אבל לטלטל אסור

The Gemara raises a difficulty: Wasn’t it stated about this law that Rav Naḥman said: They taught that such a partition is called a partition only as a stringency, in that it is prohibited to throw from an area enclosed by such a partition into the public domain and vice versa; but to carry within it as a full-fledged private domain is prohibited. This implies that these are not proper partitions.

כי איתמר דרב נחמן אמזיד איתמר

The Gemara refutes this objection: When that statement of Rav Naḥman was stated, it was stated with regard to a case where one erected the partition intentionally. Since one intentionally violated Shabbat when he erected the partition, the Sages imposed a penalty that he is prohibited to carry within the enclosed area. But if the partition was made unwittingly or came about by itself, no such penalty was imposed, and one is permitted to carry.

ההיא איתתא דעבדה מחיצה על גבי מחיצה בנכסי הגר אתא ההוא גברא רפק בה פורתא אתא לקמיה דרב נחמן אוקמה בידיה אתת איהי וקא צווחא קמיה אמר לה מאי איעביד לך דלא מחזקת כדמחזקי אינשי

The Gemara cites a related incident: A certain woman erected a partition on top of another partition in the property of a deceased convert. A certain man then came and plowed the ground a little. The man came before Rav Naḥman, who established the property in his possession. The woman then came and cried out before Rav Naḥman. He said to her: What can I do for you, as you did not take possession of the property in the manner that people take possession.

קרפף בית שלש וקירה בו בית סאה רבא אמר אויר קירויו מייתרו ורבי זירא אמר אין אויר קירויו מייתרו

With regard to a karpef the size of three beit se’a, and one roofed one beit se’a of it, the amora’im disputed whether or not the area of karpef is two beit se’a, in which case it is permitted to carry there, or three beit se’a, in which case it would be prohibited. Rava said: Its roofed space renders it in excess of two beit se’a, meaning that the roofed area is not considered separate from the rest, and so it is prohibited to carry in the karpef. And Rabbi Zeira said: Its roofed space does not render it in excess of two beit se’a, and it is permitted to carry there.

לימא רבא ורבי זירא בפלוגתא דרב ושמואל קא מיפלגי דאיתמר אכסדרה בבקעה רב אמר מותר לטלטל בכולה ושמואל אמר אין מטלטלין אלא בארבע אמות

The Gemara comments: Let us say that Rava and Rabbi Zeira dispute the same point that was the subject of dispute between Rav and Shmuel. These amora’im disagreed about the following, as it was stated: With regard to an enclosed veranda [akhsadra], which is a roofed structure without walls or with incomplete walls, in a field that has the status of a karmelit, Rav said: One is permitted to carry in the entire enclosed veranda, as it is considered a private domain. And Shmuel said: One may carry only a distance of four cubits.

רב אמר מותר לטלטל בכולה אמרינן פי תקרה יורד וסותם ושמואל אמר אין מטלטלין אלא בארבע אמות לא אמרינן פי תקרה יורד וסותם

The Gemara explains the two opinions: Rav said: One is permitted to carry in the entire enclosed veranda, since we say that the edge of the roof descends to the ground and closes up the enclosed veranda on all sides; consequently, it is considered a separate private domain. And Shmuel said: One may carry only a distance of four cubits, as we do not say that the edge of the roof descends and closes up the enclosed veranda.
