ובלבד שלא יוציא זה מתוך שלו לתוך של חברו

provided that the one does not carry anything from his four-cubit limit into that of his fellow.

היו שלשה והאמצעי מובלע ביניהן הוא מותר עמהן והן מותרין עמו ושנים החיצונים אסורין זה עם זה

With regard to a case where there were three people in this situation, and certain parts of the four cubits of the middle one were subsumed within the respective limits of each of the others, so that he shared a certain area with each of them, he is permitted to eat with either of them, and they are both permitted to eat with him; but the two outer ones are forbidden to eat with each other, since they share no common area.

אמר רבי שמעון למה הדבר דומה לשלש חצירות הפתוחות זו לזו ופתוחות לרשות הרבים עירבו שתים עם האמצעית היא מותרת עמהן והם מותרות עמה ושתים החיצונות אסורות זו עם זו:

Rabbi Shimon said: To what is this comparable? It is like three courtyards that open into one another, and also open into a public domain. If the two outer courtyards established an eiruv with the middle one, the middle one is permitted to carry to the two outer ones, and they are permitted to carry to it, but the two outer courtyards are prohibited to carry from one to the other, as they did not establish an eiruv with one another.

גמ׳ בעי רבא מאי קסבר רבי יוחנן בן נורי מסבר קא סבר חפצי הפקר קונין שביתה

GEMARA: Rava raised a dilemma: What does Rabbi Yoḥanan ben Nuri hold? Does he hold that ownerless objects acquire residence for Shabbat, i. e., even an article that does not belong to anyone acquires residence at the onset of Shabbat and can therefore be carried two thousand cubits in each direction?

ובדין הוא דליפלוג בכלים והא דקמיפלגי באדם להודיעך כוחן דרבנן דאף על גב דאיכא למימר הואיל וניעור קנה ישן נמי קנה קא משמע לן דלא

And according to this understanding, Rabbi Yoḥanan ben Nuri should by right have disagreed with the Rabbis even about utensils that were left in the field, i. e., that according to the opinion of Rabbi Yoḥanan ben Nuri, ownerless utensils can be moved two thousand cubits in each direction. And the reason that they disagreed about a person is to convey the far-reaching nature of the stringent ruling of the Rabbis, that although there is room to say: Since a person who is awake acquires for himself two thousand cubits, he also acquires them if he is sleeping, the mishna nonetheless teaches us that the Rabbis did not accept this argument, and this is why the dispute is taught specifically with respect to a person.

או דילמא קסבר רבי יוחנן בן נורי בעלמא חפצי הפקר אין קונין שביתה והכא היינו טעמא הואיל וניעור קנה ישן נמי קנה

Or perhaps we should understand his position differently, that in general Rabbi Yoḥanan ben Nuri holds that ownerless objects do not acquire residence of their own. But here, with regard to a person, the reason is as follows: Since a person who is awake acquires for himself two thousand cubits, he also acquires them if he is sleeping.

אמר רב יוסף תא שמע גשמים שירדו מערב יום טוב יש להן אלפים אמה לכל רוח ביום טוב הרי הן כרגלי כל אדם

Rav Yosef said: Come and hear a solution to this dilemma from the following baraita: Rain that fell on the eve of a Festival has two thousand cubits in each direction, meaning that one is permitted to carry the rainwater within a radius of two thousand cubits. But if the rain fell on the Festival itself, it is like the feet of all people, as it did not acquire residence, and consequently one is permitted to carry this water wherever he is permitted to walk.

אי אמרת בשלמא קסבר רבי יוחנן בן נורי חפצי הפקר קונין שביתה הא מני רבי יוחנן היא

Granted, it is understandable if you say that Rabbi Yoḥanan ben Nuri holds that ownerless objects acquire residence; in accordance with whose opinion is this baraita? It is that of Rabbi Yoḥanan ben Nuri, and consequently the rain that fell on the eve of the Festival acquired residence in the spot where it fell.

אלא אי אמרת חפצי הפקר אין קונין שביתה הא מני לא רבי יוחנן ולא רבנן

However, if you say that he maintains that ownerless objects do not acquire residence, in accordance with whose opinion is this baraita? Neither that of Rabbi Yoḥanan ben Nuri, nor that of the Rabbis, as it clearly indicates that rain acquires a place of residence even though it has no owner. Rather, we must say that Rabbi Yoḥanan ben Nuri is of the opinion that ownerless objects acquire residence, and this baraita is in accordance with his opinion.

יתיב אביי וקאמר לה להא שמעתא אמר ליה רב ספרא לאביי ודילמא בגשמים הסמוכין לעיר עסקינן ואנשי אותה העיר דעתם עילייהו

Abaye sat and recited this tradition. Rav Safra said to Abaye: Perhaps we are dealing with rain that fell near a city, and the inhabitants of that city had it in mind, and that is why it acquires two thousand cubits in each direction.

אמר ליה לא סלקא דעתך דתנן בור של יחיד כרגלי יחיד ושל אותה העיר כרגלי אותה העיר ושל עולי בבל כרגלי הממלא

Abaye said to him: It should not enter your mind that such an understanding is correct, as we learned in a mishna: A cistern that belongs to an individual, its water is like the feet of that individual, the owner of the cistern, in that it may be carried wherever he is permitted to walk. And a cistern that belongs to a particular city, its water is like the feet of the people of that city, in that it may be carried wherever the inhabitants of that city may walk, i. e., two thousand cubits in each direction from the city. And a cistern that belongs to pilgrims from Babylonia on the way to Eretz Yisrael, meaning that it belongs to all Jews and has no particular owner, its water is like the feet of the one who draws the water, in that it may be carried wherever he is permitted to walk.

ותניא בור של שבטים יש להן אלפים אמה לכל רוח קשיין אהדדי

And it was taught in a baraita:

A cistern that belongs to one of the tribes and has no particular owner, its water has two thousand cubits in each direction. If so, these two sources contradict each other, as the mishna teaches that water that belongs to the entire community does not establish residence, whereas the tanna of the baraita holds that it may be carried two thousand cubits from its place.

אלא לאו שמע מינה הא רבי יוחנן בן נורי הא רבנן

Rather, in order to resolve the contradiction, learn from here: This source, which states that the water may be carried two thousand cubits, was taught in accordance with the opinion of Rabbi Yoḥanan ben Nuri, who says that even ownerless objects acquire residence; that source, which states that water that does not belong to any particular person is like the feet of the one who draws it, was taught in accordance with the opinion of the Rabbis, who say that ownerless objects do not acquire residence.

כי אתא לקמיה דרב יוסף אמר ליה הכי קאמר רב ספרא והכי אהדרי ליה אמר ליה ואמאי לא תימא ליה מגופה אי סלקא דעתך גשמים הסמוכין לעיר עסקינן האי יש להן אלפים אמה לכל רוח

The Gemara relates that when Abaye came before Rav Yosef, he said to him: This is what Rav Safra said, and this is what I answered him. Rav Yosef said to him: And why did you not answer him from the baraita itself? If it should enter your mind that we are dealing with rain that fell near a city, how can you understand the statement that the rainwater has two thousand cubits in each direction?

הא כרגלי אנשי אותה העיר מיבעיא ליה:

According to your understanding, that the rainwater may be carried two thousand cubits because the inhabitants of the town had it in mind, the baraita should have said: The rainwater is like the feet of the inhabitants of that city. Rather, you must say that the inhabitants of the city did not acquire the water and that it may be carried within a radius of two thousand cubits, because the baraita was taught in accordance with the opinion of Rabbi Yoḥanan ben Nuri, that ownerless objects acquire residence.

אמר מר ביום טוב הרי הן כרגלי כל אדם ואמאי ליקני שביתה באוקיינוס

The Gemara further examines the baraita cited earlier. The Master said: If rain fell on the Festival itself, it is like the feet of all people. The Gemara raises a difficulty: And why should this be? The water should have acquired residence in the ocean [okeyanos], where it was when the Festival began. And since the water went out on the Festival beyond its limit after it evaporated and formed into clouds, moving the water more than four cubits should be prohibited.

לימא דלא כרבי אליעזר דאי כרבי אליעזר הא אמר כל העולם כולו ממי אוקיינוס הוא שותה

Let us say that this baraita was taught not in accordance with the opinion of Rabbi Eliezer. Because if it is in accordance with the opinion of Rabbi Eliezer, he said: The entire world drinks from the waters of the ocean; that is to say, evaporated ocean water is the source of rain.

אמר רבי יצחק הכא בעבים שנתקשרו מערב יום טוב עסקינן

Rabbi Yitzḥak said: Here we are dealing with clouds that were already formed on the eve of the Festival. Since these clouds were already formed before the Festival, the water did not acquire residence in the ocean or travel beyond its limit on the Festival.

ודילמא הנך אזלי והנך אחריני נינהו דאית להו סימנא בגוייהו

The Gemara asks: But perhaps those clouds that had already been formed on the eve of the Festival went away, and these clouds, from which the rain fell, are others that did acquire residence in the ocean? The Gemara answers: We are dealing here with a case where there is an identifying sign that these are the same clouds and not others.

ואיבעית אימא הוי ספק דדבריהם וספק דדבריהם להקל

And if you wish, say that there is another reason we are not concerned that these might be other clouds: This matter of whether or not they are the same clouds pertains to an uncertainty with respect to a rabbinic law, and the principle is that with regard to an uncertainty concerning a rabbinic law, one may follow the lenient understanding.

וליקני שביתה בעבים תיפשוט מינה דאין תחומין למעלה מעשרה דאי יש תחומין ליקני שביתה בעבים

The Gemara asks: Let the water acquire residence in the clouds, where it was when the Festival began, and its limit should be measured from there. Since the baraita taught that the water is like the feet of all people, if so, resolve from here another dilemma, and say that there is no prohibition of Shabbat limits above ten handbreadths, and one is permitted to travel more than two thousand cubits above this height. For if there is a prohibition of Shabbat limits above ten handbreadths, let the water acquire residence in the clouds.

לעולם אימא לך יש תחומין ומיא בעיבא מיבלע בליעי

The Gemara rejects this argument: Actually, I can say to you: There is a prohibition of Shabbat limits even above ten handbreadths, and the water does not acquire residence in the clouds because it is absorbed in the clouds. Since water does not exist in its usual state within the clouds, but rather takes on a different form, it does not acquire residence there.
