When the inhabitants of a courtyard eat at the same table1The Kessef Mishneh explains that the Rambam's wording is not to be understood literally; if people eat in the same room, even if they eat at different tables - indeed, even if they eat their own food - they are not required to establish an eruv. These concepts are also reflected in the Rambam's Commentary on the Mishnah (Eruvin 6:7) and quoted as halachah by the Ramah (Orach Chayim 370:4).The most common application of this concept today would be a hotel or a bungalow colony, where many people eat in the same dining room, and yet have their own private rooms or dwellings. - even though they have their own individual dwellings - they are not required to establish an eruv; they are considered to be the inhabitants of a single household.
Just as the presence of a person's wife, the members of his household, or his servants does not cause him to be forbidden [to carry], nor does their presence make an eruv necessary, so too, these individuals are considered to be the members of a single household, for they all eat at the same table.2This highlights the principle that it is the place where a person eats, and not where he sleeps, that is most significant in defining his place of residence.

Similarly, if [the inhabitants of this courtyard] must establish an eruv together with the inhabitants of another courtyard, they are required to bring only one loaf to the place where the eruv is established.3In Chapter 1, Halachah 15, the Rambam states that every household participating in the eruv is required to contribute a loaf of bread. Nevertheless, in this instance, since all the inhabitants of the courtyard are considered to be members of a single household, only one loaf is required.Similarly, if the eruv is established in their [house], they do not have to contribute to the eruv, just as the house in which an eruv is placed does not have to contribute a loaf of bread. [The rationale for both these laws is] that all these dwellings are considered to be a single dwelling.

Similarly, the inhabitants of a courtyard who established an eruv together are considered to be [the members of] a single household.4Although they eat in separate places, joining together in the eruv causes them to be considered as if they share the same table. If it is necessary for them to establish an eruv together with the inhabitants of another courtyard, they are required to bring only one loaf to the place where the eruv is established. Similarly, if the eruv is established in their [house], they do not have to contribute a loaf of bread.הלכה ד

When five people collect an eruv5I.e., they collected loaves of bread from each household in the courtyard. [for one courtyard] with the intent of bringing it to the place where an eruv will be established [together with the inhabitants of another courtyard],6The Shem Yosef explains that this latter phrase represents the new concept contributed in this halachah, as opposed to the previous one. Although the eruv was originally collected for the purpose of establishing an eruv with the inhabitants of another courtyard, the collection itself causes the inhabitants to be considered members of a single household. it is not necessary for all five to bring the bread there. Moreover, all th at is necessary is to bring a single loaf of bread. Since the eruv was collected, all [the inhabitants of the courtyard] are considered to be the members of a single household.הלכה ה

[The following rules apply to] brothers, each of whom has a house of his own, and who do not eat at their father's table, and to wives and servants who do not eat at their husband's or master's table at all times, but rather they [occasionally] eat at his table in payment for the work they do for him,8The Rambam's comparison of these individuals to hired workers reflects his interpretation of the expression במקבלי פרס in Eruvin 73a. The Ra'avad offers a different interpretation, and his view is quoted in the Shulchan Aruch (Orach Chayim 370:5- 6). or as an expression of his favor for a specific amount of time, such as a person who enjoys a colleague's hospitality for a week or a month.9The Maggid Mishneh explains that the Rambam's intent is not that the presence of a guest causes carrying to be forbidden when there are others living in the same courtyard. For as explained at the beginning of Chapter 2, and in Halachah 12 of this chapter, a guest's presence makes no difference in this context. Rather, the point of the comparison above is to emphasize the intermediate status of these individuals. On one hand, like guests, they are at times considered to be members of the person's household. On the other hand, since they have their own dwellings and often eat there, there is reason to consider them as having separate households.If there are no other people dwelling together with them in the courtyard, they are not required to establish an eruv. If they establish an eruv with [the inhabitants of] another courtyard, a single eruv suffices for them. If the eruv is established in [one of] their [homes], they are not required to contribute a loaf of bread.
If there are other people living in the courtyard together with them, each of them is required to contribute a loaf of bread [for the eruv] like the other inhabitants of the courtyard. [The rationale is that] they do not eat at one table at all times.

[The following rules apply when] five groups spend the Sabbath together in a single large hall: If a partition that reaches the ceiling10The Maggid Mishneh cites the Rashba, who explains that it is sufficient for the partitions to reach within three handbreadths of the ceiling, since, based on the principle of l'vud, when they are that close it is considered as if they reached the ceiling itself. The Shulchan Aruch (Orach Chayim 370:3) quotes this ruling. separates each of the groups [from the others], it is as if each group has a room of its own, or is in a loft of its own. In such an instance, every group must contribute a loaf of bread. If, however, the partition does not reach the ceiling, a single loaf11I.e., they must make an eruv. The Shulchan Aruch (loc. cit.) differs and (following the interpretation of Tosafot, Eruvin 72a and Rabbenu Asher) does not require an eruv at all unless they want to join with others outside the hall.The Shulchan Aruch, however, emphasizes that we are speaking about temporary partitions, either curtains or pieces of wood. If the partitions are permanent, they are considered as having separate dwellings, and an eruv is required.of bread is sufficient for all of them. For they are all considered to be the members of a single household.

When a person owns one [of the following] structures12All these structures have one thing in common - they are not ordinary dwellings where a person will eat his meals on a regular basis. - a gatehouse that people frequently walk through, an exedra,13A Greek structure with two or three walls and a roof with a sky-light.a porch, a barn, a shed for straw, a shed for wood, or a storehouse - in a courtyard belonging to a colleague, he does not cause [his colleague] to be forbidden to carry. [Our Sages decreed that the presence of a person causes carrying] to be forbidden unless an eruv is established, only when the person possesses a dwelling in the courtyard in which he will [ordinarily] eat [a meal of] bread. The [possession of a] place to sleep, by contrast, does not cause carrying to be forbidden.For this reason, even if a person decided to eat his meals consistently in a gatehouse or an exedra, his presence does not cause carrying to be forbidden, because this is not considered a dwelling.14For these structures are not fit to serve as dwellings. In contrast, were a person to eat continually in a barn, a wood shed, or a shed for straw, these are considered to be dwellings, and an eruv is necessary (Shulchan Aruch, Orach Chayim 370:1; see Chapter 1, Halachah 16).

[The following rules apply when] there are ten dwellings, one within the other:15I.e., to get to the inner dwellings, one must pass through the outer ones. [The inhabitants of] the innermost dwelling and the one before it are required to provide the eruv. The eight outer dwellings, by contrast, are not required to contribute to the eruv. [The rationale is that] since many people walk through them, they are regarded as a gatehouse. [As mentioned above,] a person who lives in a gatehouse [does not cause others to be forbidden to carry].16The Mishnah Berurah 370:52 extends this principle and applies it to people renting separate rooms in a single home. If the rooms lead through each other, the inhabitants of the outer rooms do not have to contribute to the eruv.[The person living in] the ninth [house] does not have many people passing through his property - only one. Therefore, his presence causes [carrying] to be forbidden unless he contributes to the eruv.

Although one of the inhabitants of a courtyard is in the midst of his death throes,19This reflects a general principle in Torah law. Until a person actually stops breathing, he is considered to be alive. There is no difference in his status regarding any of the Torah's laws. even when [it is obvious] that he will not survive the day, his presence causes the other inhabitants of the courtyard to be forbidden [to carry] until they grant him [by proxy]20See Chapter 1, Halachah 20. a share in a loaf of bread and include him in the eruv.Similarly, when a minor [owns a house in the courtyard], although he is incapable of eating an amount of food the size of an olive, his presence causes [carrying] to be forbidden until [the inhabitants of the courtyard] include him in the eruv. [The presence of] a guest, by contrast, does not cause [carrying] to be forbidden, as explained above.21See Chapter 2, Halachah 1.

[The following rules apply when] one of the inhabitants of a courtyard leaves his home and spends the Sabbath in another courtyard, even in a courtyard adjacent [to the one in which his home is located]: If he had no thought of returning to his home on the Sabbath, he does not cause [carrying] to be forbidden.22The rationale is that a dwelling without an owner is not considered to be a dwelling (Shulchan Aruch HaRav 371:1; Mishnah Berurah 371:1).When does the above apply? With regard to a Jew.23For it is unlikely that a Jew will return to his home on the Sabbath. Moreover, even if he did so, we apply the principle that since carrying was permitted for a portion of the Sabbath, it is permitted for the entire Sabbath (Maggid Mishneh). With regard to a gentile, by contrast, he causes [carrying] to be forbidden even when he spends the Sabbath in another city,24The Maggid Mishneh mentions a more lenient view, which states that if the gentile spends the Sabbath at a place that is more than a day's journey from home, the inhabitants are allowed to carry, because it is impossible for him to arrive on the Sabbath. This ruling is quoted by the Shulchan Aruch (Orach Chayim 371:1).
The Ramah grants a further leniency and permits the inhabitants to carry when the gentile stays in another courtyard in the same city. If the gentile returns to his home on the Sabbath, the Turei Zahav 371:2 permits the inhabitants to continue to carry. The Mishnah Berurah 371:8, by contrast, rules that this is forbidden. unless his domain is rented from him. [The rationale is] that it is possible for him to return on the Sabbath.

When the owner of a courtyard rents houses in the courtyard to others and [stipulates that] he may [continue] to leave articles or types of merchandise in each of these homes, [the presence of the renters] does not cause [carrying] to be forbidden. Since he still has authority in each of the houses, everyone is considered to be his guest.25Note the ruling of the Ramah (Orach Chayim 370:2), which states that this decision applies only when there are no other inhabitants in the courtyard besides the owner and the persons to whom he rented dwellings, or the eruv was brought into the house of the owner.When does the above apply? When he left an article that may not be carried26The Shulchan Aruch (loc. cit.) adds that this applies also when the articles are too heavy to be lifted on the Sabbath. on the Sabbath - e.g., tevel27Produce from which terumah and the tithes have not been separated. These tithes may not be separated on the Sabbath (Hilchot Shabbat 23:9,14), nor is it permitted to carry such produce on the Sabbath (loc. cit. 25:19). or slabs of metal,28Since this metal has not been fashioned into a useful article, it is forbidden to be carried on the Sabbath (loc. cit.:6). in these homes. When, by contrast, he leaves articles that may be carried in each of the homes, [the presence of the renters] causes [carrying] to be forbidden unless they establish an eruv. For it is possible that he will remove them [on the Sabbath], and then he will be left without any authority [in these dwellings].

[The following rules apply when] the inhabitants of a courtyard forgot and did not establish an eruv. They may not remove articles from their homes to the courtyard, nor from the courtyard to their homes. However, concerning articles that were left in the courtyard at the commencement of the Sabbath:29See the Be'ur Halachah 372, which explains there are authorities who differ with regard to whether one is permitted to carry an article within a courtyard when an eruv has not been established - if that article hads been placed in one of the homes at the commencement of the Sabbath, but was inadvertently taken from the home and placed in the courtyard. Although the Rambam would appear to forbid carrying the article, Rashi (Shabbat 130b) and Tosafot (Eruvin 91b) maintain that carrying it is permitted within the courtyard. [the inhabitants] may carry such articles throughout the courtyard and all its extensions.30See Chapter 3, Halachah 19.[The following rules apply when] there is a porch31In his Commentary on the Mishnah (Eruvin 8:3), the Rambam describes a porch as an intermediate level, at least ten handbreadths high, through which stairs lead to the courtyard. or an upper storey [that opens out to a courtyard],32I.e., the inhabitants of the porch or the upper storey descend through a stairwell into the courtyard, and from the courtyard they proceed to the public domain. The Rabbis consider the stairwell equivalent to an entrance. Hence, they liken the situation to one in which two courtyards are positioned adjacent to each other with an entrance between them. and the inhabitants of the courtyard have established an eruv for themselves and the inhabitants of the porch have established an eruv for themselves:33I.e., unless an eruv is established, the inhabitants of these domains are forbidden to carry within the others' domains and within the property shared by both. Regarding articles that were left in their homes at the beginning of the Sabbath, the inhabitants of the porch or the upper storey are permitted to carry them throughout the porch and all of its extensions or throughout the upper storey and all of its extensions. The inhabitants of the courtyard may carry within the courtyard and all its extensions, [but they are forbidden to carry from the courtyard to the upper storey or the porch, or from the upper storey or the porch to the courtyard unless an eruv is established].
Similarly, if one person lives in the courtyard, and another person lives in the upper storey, and they forgot to establish an eruv, the owner of the upper storey may carry within the upper storey and all of its extensions, and the owner of the courtyard may carry within the courtyard and all of its extensions. [They may not, however, carry from one domain to the other without an eruv].

What is implied? When there is a rock or a mound within the courtyard that is less than ten handbreadths high, it is considered to be [important to] both the courtyard and the porch, and [the inhabitants of] both are forbidden to bring articles there from their homes.If [the rock or the mound] is ten handbreadths high and is less than four handbreadths removed from the porch, it is considered to be an extension of the porch, for they are of similar [height]. Therefore, the inhabitants of the porch may carry on it.
If it is four or more handbreadths removed from the porch, even when it is ten [handbreadths high] it is considered to be an extension of both the courtyard and the porch, since both can use it by throwing [objects onto it]. Therefore, [the inhabitants of] both are forbidden to bring articles there from their homes until they establish an eruv.
When there is a pillar four [or more] handbreadths wide in front of the porch [it is considered to be a divider]. [Therefore, the presence of] the porch does not cause [carrying] to be forbidden within the courtyard, for a separation has been made between [one domain and the other].

[The following rules apply when] there are two courtyards, one lying behind the other, and the inhabitants of the inner courtyard enter and exit by passing through the outer courtyard: When [the inhabitants of] the inner courtyard have established an eruv, but [the inhabitants of] the outer courtyard have not, [the inhabitants of] the inner courtyard may carry [within their domain], but [the inhabitants of] the outer courtyard may not.37The rationale for these rulings is obvious; the concept is mentioned primarily to show the contrast with the subsequent clauses of the halachah. Unlike the inhabitants of the inner courtyard, who can reach their own dwelling only by passing through the outer courtyard, there is no reason for the inhabitants of the outer courtyard to pass through the inner one.When [the inhabitants of] the outer courtyard have established an eruv, but [the inhabitants of] the inner courtyard have not, [the inhabitants of] both are forbidden to carry; [the inhabitants of] the inner courtyard because they did not establish an eruv, and the inhabitants of the outer courtyard because the people who pass through [their domain] did not establish an eruv [even within their own domain].38This ruling reflects the principle stated in Halachah 23, that when people are forbidden to carry within their own domain, they cause carrying to be forbidden in the domain through which they pass. Had the inhabitants of the inner courtyard established an eruv for themselves, they would not cause carrying to be forbidden in the outer courtyard, as reflected in the following clause.
If [the inhabitants of] both domains have established separate eruvin,39Similarly, if the single courtyard belongs to a single individual, or the owners are considered to be members of a single household - e.g., a father and his children, their presence does not cause carrying to be forbidden in the outer courtyard (Maggid Mishneh). they may each carry within their own domain; they may not carry from one [domain] to the other.

If [only] one person45In his Commentary on the Mishnah (Eruvin 6:10), the Rambam explains that this can refer to members of an extended household - e.g., a father and his children. was dwelling in one [of these] courtyards and [only] one person was dwelling in the other, there is no need for them to establish an eruv;46Needless to say, to carry from one courtyard to the next, an eruv is necessary. each one is permitted to carry in his courtyard.If, however, a gentile dwells in the inner courtyard, even though he is merely a single [household], he is considered as many individuals, and [his presence] causes [the inhabitants of] the outer courtyard to be forbidden to carry until his domain is rented.47Our Sages explained that gentiles are less private about the details of their personal dwellings than the Jews. Thus many people will know of the gentile's presence and the fact that his domain was not rented, but they may not know that only one Jew lives in the outer courtyard. Therefore, they might not realize that this is an exception, and generally, when one courtyard leads to another, an eruv is required (Eruvin 75b). Although when one Jew lives in a courtyard together with a gentile, he is generally not required to rent his domain (Chapter 2, Halachah 9), an exception is made in this instance.
The Shulchan Aruch (Orach Chayim 382:17) mentions this as a singular opinion, and the Mishnah Berurah 382:59 states that it is not shared by most authorities. Some have noted that the Rambam himself uses a plural form of the word "rent," and they interpret this as referring to an instance where two Jews live in the outer courtyard.

[The following laws apply when there are] three courtyards with entrances to each other, and there are many people dwelling in each courtyard: When [the inhabitants of] the two outer courtyards have established an eruv together with [the inhabitants of] the inner courtyard,48I.e., the inhabitants of the inner courtyard have established two eruvin, one with each of the outer courtyards. [the inhabitants of] the inner courtyard are permitted to carry within the outer courtyards, and [the inhabitants of] the outer courtyards are permitted to carry within the inner courtyard, but the inhabitants of the two outer courtyards may not carry in the other outer courtyard unless all three join in a single eruv.If a single individual dwells in each courtyard, there is no need for them to establish an eruv, although many individuals pass through the outer courtyard.49The Maggid Mishneh explains that these two clauses refer to different situations. The first clause refers to a situation in which all three courtyards have entrances to the public domain, while this clause refers to a situation where only the outermost courtyard has an entrance to the public domain, and the inhabitants of this courtyard must pass through it.
Based on the Hagahot Maimoniot, Merkevet HaMishneh explains that the fundamental aspect of this ruling is the interpretation of Rabbi Shimeon's statements that the inhabitants of the middle courtyard are permitted to carry in either of the outer courtyards (Eruvin 45b, 48b). Although these statements were made regarding a situation in which only one courtyard opened up to the public domain, one can extrapolate that the same ruling would apply when all three open to the public domain. [The rationale is that] each of these individuals is permitted to carry in his own domain. If, however, there are two individuals living in the inner courtyard [different rules apply]. Since [these individuals] are forbidden to carry in their own domain until they establish an eruv, they cause the single individuals in the middle and in the outer domains to be forbidden [to carry] unless the two inhabitants of the inner domain establish an eruv.
This is the governing principle: When a person who is forbidden to carry in his own domain passes through another domain, his passage causes carrying to be forbidden there. When, by contrast, the person may carry in his own domain, his passage through another domain does not cause carrying to be forbidden there.

[The following rules apply when] there are two balconies positioned over a body of water, and one is positioned above the other: Although [the inhabitants of] each of them have constructed a partition ten handbreadths high descending [to the water],50See Hilchot Shabbat 15:15, which interprets this law as referring to a balcony with a hole in its floor, from which water is drawn and through which it is poured. The partition need not extend the full distance from the balcony to the water. As long as it extends either ten handbreadths below the balcony or ten handbreadths above the water, drawing water and pouring water through the hole in the balcony are permitted. if the two balconies are within ten handbreadths of each other,51In his Commentary on the Mishnah (Eruvin 8:8), the Rambam explains this as referring to two balconies positioned one on top of the other. Each balcony has a hole in it, and these holes are also aligned one on top of the other. it is forbidden for [their inhabitants] to draw water unless they establish a single eruv. [The rationale is that, because of their closeness] they are considered to be a single balcony.52The Ra'avad states that, based on Eruvin 88a, this ruling would appear to apply only when the two balconies are not directly above each other. The Ra'avad's position is shared by Rashi and the Rashba, while the Rambam's interpretation appears to be shared by Rabbenu Chanan'el. Although the Maggid Mishneh attempts to justify the Rambam's position, most authorities (including the Shulchan Aruch, Orach Chayim 355:5) follow the Ra'avad's view.If the distance between the upper balcony and the lower balcony is more than ten handbreadths, and [the inhabitants of] each have established separate eruvin, they are both permitted to draw [water].

If [the inhabitants of] the upper [balcony] did not make a partition, but the inhabitants of the lower [balcony] did, even [the inhabitants of] the lower balcony are forbidden to draw [water]. [The rationale is that] the buckets of the upper [balcony], which are forbidden, pass through their domain.53I.e., the Rambam applies the principle stated in Halachah 23 - about people passing from one domain to another - to the buckets used to draw water that pass from domain to domain. In this instance, as well, the Ra'avad, Rashi, and others interpret Eruvin (loc. cit.), the source for this halachah, differently, and their interpretation is cited in the Shulchan Aruch (loc. cit.).If [the inhabitants of] the upper [balcony] have made a partition, but [the inhabitants of] the lower [balcony] have not, [the inhabitants of] the upper balcony are permitted to draw water,54The fact that their buckets pass through the area of the lower domain is of no consequence. but [the inhabitants of] the lower balcony are forbidden.55For they have no partition.
If the inhabitants of the lower [balcony] joined together with [the inhabitants of] the upper [balcony] in the construction of the partition, [the inhabitants of] both are forbidden to draw water56Since they both have a share in the partition, they are considered as full partners in a single domain. Hence, it is necessary that they be joined together in an eruv. until they establish a single eruv.
