communities. An eruv accomplishes this by symbolically integrating a number of private properties and spaces such as streets and sidewalks into one larger "private domain" by surrounding it with '' mechitzas'', thereby avoiding restrictions of transferring between domains. Often a group constructing an eruv obtains a lease to the required land from a local government. An eruv allows Jews to carry, among other things, house keys, tissues, medication, or babies with them, and to use strollers and canes. The presence or absence of an eruv thus especially affects the lives of strictly observant Jews with limited mobility and those responsible for taking care of babies and young children.

The rules here are complex, and expertise is needed to apply them. On Shabbat, it is forbidden to transfer an object from one domain to another, including from one person's house to another adjacent house. The only exception is transferring to or from a neutral domain (which is rarely relevant). In addition, it is also forbidden to transfer an object for a distance of 4

''Eruv chatzerot''

The term eruv is a shortening of ''eruv chatzerot'' (), literally a "merger of ifferentdomains" (into a single domain). This makes carrying within the area enclosed by the eruv no different from carrying within a single private domain (such as a house owned by a single person), which is permitted. The eruv typically includes numerous private homes, as well as a semi-public courtyard whose ownership is shared by them. To enact the merger of the homes and courtyard into a single domain, all home owners as well as owners of the courtyard must pool together certain foodstuffs, which grants the area of the eruv the status of a single private domain. As a precondition for this merger, the area must be surrounded by a wall or fence. In many cases (for example, within an apartment complex or walled city) the demarcation of the shared area consists of real walls or fences. Building walls may also be used, and in some cases so may a natural wall such as a river bank or steep hill. Walls may include doors and windows. As such, the wall may even consist of a series of "doorframes" with almost no wall between them. Poles in the ground form the "doorposts" of the doorframe, and rope or wire between the poles forms the "lintel" of the doorframe. In modern cities, it is typical for the majority of an eruv to consist of such doorframes, using
utility pole A utility pole is a column or post typically made out of wood used to support overhead power lines and various other public utilities, such as electrical cable, fiber optic cable, and related equipment such as transformers and street lights. I ...
s and wires. When a "doorframe" is used as part of an eruv, it is required that the "lintel" rest on top of the "doorpost", rather than being attached to the side of the "doorpost". Since the "lintel" is frequently a utility wire which runs along the side of the utility pole, the pole cannot be used as "doorpost". In this case, an additional "doorpost", known in Hebrew as a (pl. ''lechai'in''), is attached to the side of the utility pole. This typically takes the form of a thin plastic pipe attached to the side of the utility pole, and the wire runs directly overhead of this pipe. Within the walled area, a property transfer is needed to create the shared domain. This is formally effected today by having one resident give some "bread" to another resident to keep, to create a joint ownership of food for the whole community. This is usually done by the

to ensure that it will be edible and usable for a long time. (It is usually replaced once each year.) In the Talmud and other classic rabbinic sources, the term eruv refers to the bread itself. A typical modern eruv encloses public streets as well as private houses, and thus requires agreement from the government authorities controlling those streets. Creating an eruv that involves public property requires that a government entity grant permission in order for the eruv to be valid. This is often done by issuing a symbolic proclamation which has no weight in

was permitted because the city had an eruv bounded by the city walls, while carrying through the gates would mean carrying outside the eruv, thus Jeremiah's criticism focused on the latter form of carrying. While the Talmud limits the permission to carry to cities where the city gates are locked at night, the view that an entire city could have an eruv influenced later views that an eruv could encompass a "courtyard" covering a wide area.


Specific laws of eruv

In general, authorities agree that eruvin are subject to certain restrictions. For example, they can be located in only certain places, and may not be of indefinite size. A prohibition against walking too far outside city boundaries (''techum'', see
Eruv techumin An eruv techumin (Hebrew: עירוב תחומין, "mixed borders") for traveling enables Jews to travel on Shabbat or a Jewish holiday, without violating the prohibition of techum shabbat. They prepare food prior to Shabbat or the holiday on whi ...

im'' (about 1 meter) in height. The laws of eruv differ depending on whether the eruv contains only private domains and ''carmelit'', or else public domains (''reshut harabim deoraita'') as well. If public domains are not included, the eruv wall may include "doorways" constructed out of wire and posts, with no actual door in them. If public domains are included, the wall must be an actual wall – every "doorway" must have a door in it, and these doors must be closed each night. This situation was common in ancient

, but is rare nowadays. So in practice, eruvin are only built in areas that do not include a public domain. What constitutes a "public area" is debated. The strict opinion holds that any road more than 16 cubits wide is a public domain, while the lenient opinion holds that a public domain must have both 16 cubits of width and 600,000 people passing through the road on a single day. In practice, communities that build eruvin accept the lenient opinion. However, in a few large cities such as

, it is possible that more than 600,000 people pass through certain roads in a single day. This would prevent building an eruv there even according to the lenient opinion. This possibility is the source of debates in New York City over whether a particular eruv, or any eruv is valid. In addition, the size of an eruv can be limited by a number of practical considerations. For example, the requirement that the eruv boundary be thoroughly checked each week and any needed repairs made before sunset on Friday limits the area that can be practically covered by a manageable eruv. The sensitivity of utility and public works crews about disturbing eruv-related attachments when making repairs can vary widely. Political and institutional differences, or differences about the correct interpretation of the relevant

Checking the eruv

The boundaries of an eruv must be checked regularly. If the boundary is not complete and contiguous in every element (''i.e.'', one of the elements of the boundary is missing or broken), no valid eruv can exist that Shabbat, and carrying remains prohibited. Eruv associations generally maintain hotlines or web sites informing communities of the status of the eruv on Friday afternoon.


Activities prohibited even within an eruv

Though a valid eruv enables people to carry or move most items outdoors on Shabbat, all other Shabbat restrictions still apply. These prohibitions include: * Handling (or, according to some, moving) objects that are '' muktzeh'', whether indoors or outdoors. * Opening an umbrella, which is analogous to erecting a tent, and falls under the category of construction. Since umbrellas may not be opened, they are muktzeh. * Typical weekday activities (''uvdin d'chol''), 'to protect the sanctity of Shabbat'. The precise scope of this prohibition is subject to a wide range of rabbinic opinion. * Moving or carrying items in preparation for a post-Shabbat activity (''hakhana''), unless one has a legitimate use for them on Shabbat itself. * Many sports and sport-related activities: Many authorities consider balls ''muktzeh''; others do not. In general, sports that result in holes or ruts being carved into the playing surface may be played only on surfaces that are not subject to such damage. Exercise of any kind is only permitted on Shabbat if done for the pleasure of the activity itself, rather than for other reasons such as health.


Disagreements among Orthodox groups

There exists disagreement between rabbis about some of the technical requirements of a valid eruv. Thus, there are instances where Orthodox rabbis dispute the validity of a particular eruv (and therefore instruct their followers not to use it), or even dispute whether any eruv can be built in a certain location. One of the oldest halakhic disputes in the United States revolves around the issue of an eruv in

with respect to carrying a burden. Therefore, Conservative Judaism's rabbinate requires the use of an eruv for ordinary carrying outside this exception.

Coping without an eruv

Many of those living in areas without an eruv are accustomed to life without one and have adapted their Shabbat practices accordingly. However, those who live in a place that has an eruv and are visiting a place without one, or if the eruv is temporarily out of service (perhaps due to wind or snow damage), may have difficulty making adjustments. Equally, those with young children, certain medical complaints, and certain disabilities often feel trapped during Shabbat. Even without an eruv, there is no problem with wearing clothing outside, provided that it is normal clothing and being worn in its normal manner, as it is considered secondary to, and "part of" the person themselves. The same is true for most medical items that are attached to the body and can be considered secondary to it, such as a cast, a bandage, or eyeglasses. Rabbinic authorities historically have differed about the use of a

In recent years, however, the majority of poskim have leaned toward allowing these devices, since, if they were prohibited, disabled individuals might attempt to leave their homes on Shabbat without the device(s) and therefore risk serious injury. Loose medicines may not be carried; most authorities have agreed that it is preferable that one who constantly needs medication remain at home rather than transgressing Shabbat by carrying medication. But, if such a person leaves home, then comes in need of medication, it is permissible under the laws of

to break Shabbat and bring the medication to the person. A small number of authorities in recent years have been permitting carrying the medication, however, since such a person may be tempted to leave home without it, and then his/her life may be endangered thereafter. Many authorities allow the wearing of jewelry by women. As for a wristwatch, it could be seen either as an adornment (permitted to wear) or as a tool (forbidden to carry); therefore opinions are divided on whether men may wear wristwatches. In communities without an eruv, it is customary to create belts, bracelets, necklaces, or similar wearable objects incorporating housekeys so that the keys can be worn rather than carried when going outdoors. To be validly "worn" rather than "carried", the key needs to be an integral part of the belt, bracelet, or other item rather than simply attached to it. It may be either an adornment if worn in a manner visible to others or a component needed to keep the wearable object fastened. Special "shabbos belts" and similar items that incorporate this property are sold in religious stores. A

Demographic changes

Jewish people who are not in favor of an eruv may feel that after an eruv is created they live in a symbolically segregated community. "It's like social engineering," said Arnold Sheiffer, founder of the opposition group Jewish People for the Betterment of Westhampton Beach. "We he Jewish peoplefought like hell to get out of the

and now they want to create that again. The opposition in the village here is very, very high."

. In the 2002 decision on ''Tenafly Eruv Association v. Borough of Tenafly'', Judge Ambro, writing for the United States Third Circuit Court of Appeals, held that Eruv Association members had no intrinsic right to add attachments to telephone poles on Borough property and that the borough, if it wished, could enact a general, neutral ordinance against all attachments to utility poles that could be enforced against the eruv. However, Judge Ambro held that in this case, the Borough had not enacted a genuinely general or neutral ordinance because it permitted a wide variety of attachments to utility poles for non-religious purposes, including posting signs and other items. Because it permitted attachments to utility poles for secular purposes, the court held, it could not selectively exclude attachments for religious purposes. The United States Supreme Court declined to hear the case. It was subsequently cited as precedent by a number of other federal courts deciding disputes between an eruv association and a local government. In

. After some eruvin were extended into Bergen County, allowing travel in the area, the municipalities took action in 2017 to dismantle the markings. The matter was taken to court, and in January 2018 the presiding judge in the lawsuits made it clear he felt the municipalities did not have a strong case, and urged them to settle. The three municipalities settled with the eruv association, allowing the eruv borders to remain in New Jersey, reimbursed the association's legal fees, received agreement from the association to adjust the color of the mounted on local utility poles, and agreed to work through a few remaining route details. In general, state law has dealt with whether and to what extent government can permit or assist the erection and maintenance of boundary demarcations on public property. It has not dealt with the nature of the aggregation agreement or recognized an eruv as having legal effect or as implementing a meaningful change in real property ownership or tenancy.

''Eruv tavshilin''

An ''eruv tavshilin'' ( he, עירוב תבשילין, , mixed cooked food items) is made in the home on the eve of a holiday with a work prohibition, if the holiday happens to fall on Friday. Since food cannot be cooked on Shabbat, the only way to eat freshly cooked food on Shabbat is to cook it on Friday, which in this case is a holiday. The ''eruv tavshilin'' allows this cooking to be done in a way that does not violate the holiday work restrictions.
