How do you know if it is still up and kosher? An eruv isn’t something you can just set up and forget about

The Rebbe was against an Eruv in Crown Heights

There is nothing else for a Chosid to say or offer an opinion about it.!

“There are those that cause conflict and confusion about eruvin, but its obviously a mitzvah according to the gemora, and you must make a brocha on it etc etc.
And we see that thru this we are saved from some severe transgressions”.
“ישנם הרבה מערערים על העירובין, אבל בפשטות על פי הש”ס זה מצווה, וצריך לברך על זה בשם וכוליה וכוליה, ומה שרואים בפשטות שעל ידי זה נזהרים כמה וכמה מעניינים חמורים”

To say the Rebbe was against making a eruv is like saying not to build a sukka, it’s divrei kfira!!

Crown Heights cannot have a Eruv Because if the Eruv Is broken people will still carry . the argument Is Not if you could make a Eruv The argument is what are community is gonna look like And that’s why the Lubavitcher Rabbi Was against it

January 20, 2022 4:19 am

The concern you raise about it breaking could happen anywhere. Nevertheless, the chachomim enacted this Mitzva.
In other words, this concern isn’t considered da concern when weighed against the benefit.

What does the community look like on Wednesday? U think Eruv is the issue ? Let them have it … people who want to use it will use it others will obstain and Sholom al yisroel … that’s whT the rebbe really had nachas from … Sholom amongst brothers

couse the rabbonim agreed to it by ch it’s diffrent even if the eruv is checked just becouse of the fact that the rabbbonim don’t allow it

Why is ch different?

Almost Every frum community in the world’s has an eruv and figures out how to deal with what happens when it’s down, why should ch be different?

Reply to  Crown Heights
January 23, 2022 10:44 am

Bro you can easily attach a low voltage wire to the eruv and indicators will prevent people from carrying when it’s down.
The concept of an eruv probably wouldn’t exist in halacha if there was concern about the eruv falling down.
But I’m no expert.

The rebbe's opinion is clearly against!
January 19, 2022 11:43 pm

מפורסמת דעתי שבדורנו זה איש או ארגון שמתחשבים אתו העושה עירוב ויודע שסוף סוף יתפרסם הדבר – הרי זה תקלה איומה, כי אי אפשר שלא יארע שבת קודש אחד והעירוב פסול – ועל פי טבע שיתרגלו פעמים אחדים בהוצאה בשבת קודש לא תועיל כל הכרזה והודעה שהעירוב נפסל ואסור וכו’ שיפסיקו להוציא,

ואין לעשות עירוב אלא בסודיות.

this answer was to a eruv that wasnt kosher enough to make a bracha since they used the ocean as a mechitza.

January 21, 2022 9:15 am

The Rebbe instructed shluchim to make a eruv without delay (see video below), when it is done with a expert.
Melbourne answer was because it wasn’t kosher according to shulchan aruch.


I mean if the Rebbe was against it,

The whole discussion is moot. Rabbi Kalmanson has a valid point in general, but to Crown Heights it’s not nogea.

January 20, 2022 10:01 am

hmm only the rebbe said it more then forty years ago, and many many times. as far as to why he didnt actually make an eruv is a separate question, that has most likely to do with the fact, that crown heights is not surrounded by electric wires, so the only way to make an eruv, is by getting permits to use city poles, which they did not have at the time. but one thing is very crystal clear the rebbe held that we did not have a rhr, same with tzemach tzedek, and the alter rebbe. so if someone… Read more »

even if the rabbiem were fine with it the rabbonnim of ch said no and by any matter of halcha the rebbe wuld rely on the rabbonim so if they somthing that doesn’t sound logical to you at the end of the day we have to follow the rabbonim of our comunitty

This is clear as can be. End of story.

January 21, 2022 12:34 pm

how do you come to this conclusion? until you have proof its obviously not true as it would opposite of halacha which tells you to build a eruv.

This whole pilpul is good and fine BUT: 1. This whole Torah is if you need 600,000 or not to make it a rashus harabim etc. Many Rabonim hold that Brooklyn and many cities around the world have 600,000 and meet the required rashus harabim. 2.The Alter rebbe said that in his time, that is two hundred years ago that there were no such cities. 3.I understand that the Rebbe was against building an eruv in n.y. 4. Most Rabbonim of Crown Hights were against making an eruv and individuals have no right making such an eruv if the Rabonim… Read more »

The alter Rebbe and almost all poskim pasken 600k have to be one street that is straight across the city, therefore we don’t have reshus harabim these days.
The Rebbe supported eruv in in big cities.
Local rabbonim cannot stop a eruv, as you can read the רא”ש the Rebbe quotes.
The alter Rebbe is not machmir on the contrary didn’t hold of the chumros in eruvin.

Can someone clarify the “need” for an eiruv? :
If today there’s no
“רשות הרבים “דאורייתא
then What’s the “need” to make an eiruv “just in case a person might cary and therefore *transgress* the shabbos”
What type of “transgression” is done by carrying an object from a רשות היחיד to a “non” רשות הרבים ??

Unless you don’t want to keep תורה שבעל פה you can’t carry into a karmelis which means any place that is open without walls 10 tefachim high surrounding it

just for accuracy’s sake both the issur to carry from a reshus hayachid to a reshus harabim and vice versa and the issur of carrying from a karmelis to one of the above reshuyois and vice versa are not clearly stated in torah shebiksav, the diffrence between them being is that one is a de’oiraysa and one a derabanan.

The holy Shinever Ruv, a son of the Divrei Chaim, once came to the town of Limanov. Understandably, the crowds came running to be blessed by the Tzaddik. As he was leaving the town a few childless couple’s blocked the pathway and started crying for a yeshuah. The Rebbe started yelling at the people; “there is no eiruv in town!” Please support the construction of an eiruv, so everyone who wants to carry may carry!” It is said that everyone who participated in building that eiruv merited great yeshu’os—specifically those who were unable to have children, and thus merited to… Read more »

I personally spoke to rabbonim, specifically Rabbi Tzinner and he told me the CH eruv is 100% kosher (alter rebbe). unsure what more you would need than that!

January 20, 2022 8:38 am

Therefore, to quote the Chassam Sofer which the Rebbe quoted “השכל הפשוט גוזר שראוי ומחוייב לתקן החצרים והמבואות בעירוב המתיר טלטול” it is simple logic that we must make an eruv for our courtyards and streets

ironic how all these people, who have obviously never learned eruvin, are arguing against the top talmidei chachomim in chabad, who have research this issue extensively, and have come to a very firm conclusion.

i guess that its a continuation of all the expert googlers that know better then all doctors etc.

As can be evident from the total lack of any comment relating to the original article and attached kuntres. I assume no one —despite having plenty to say on the topic— as the rosh required to actually read through the kuntres and form an intelligent (intelligible?) opinion.

with all due respect

at the end of the day the anash should listen to the rabbanim of crown hights no matter if another respected rabbi from elsewhere holds that it is ok we should listen to our rabbanim from ch no matter what.

Did ANYONE actually READ the Kuntres?
January 22, 2022 3:36 pm

Rabbi Kalmenson’s Kuntres is fantastic. It is about whether we go by the opinion that a Reshus HaRabim MidOraisa is a) a city with a highway that is 16 Amos wide (a bit over 24 feet) or b) a city with 600,000. It is irrelevant to New York City, which is 600,000. Reb Moshe Feinstein found a heter for Sea Gate, which was to build a gate separating it from the rest of NY. There is no other way to section off Crown Heights from the rest of Brooklyn. In a sicha in the Mems (1980s) the Rebbe brought an… Read more »

Cities are not a רשות הרבים
Reply to  Did ANYONE actually READ the Kuntres?
January 23, 2022 8:02 am

Three reasons why Brooklyn (and other cities) are not a רשות הרבים according to the אדמו”ר הזקן.
1. don’t have ששם ריבוא בוקאים בו בכל יום במבוי.
600k on one street. ( We don’t count the city as a whole)
2. Roads are not מפולש. Roads have to be straight across city with no obstacles like street lights etc..
3. Surrounded by רוב מחיצות with מחיצות הבתים and has walls on fences along coast.

Like most poskim, Rav Moshe originally maintained that the criterion of shishim ribo was dependent on the street having shishim ribo traversing it. However, he later formulated his chiddush in which shishim ribo, when applied to a city, was not dependent on a street but over a twelve mil by twelve mil area [approximately 8.1 by 8.1 miles]. Rav Moshe added that the criterion of shishim ribo ovrim bo would require a sizable population living and commuting into the twelve mil by twelve mil area so that it could physically satisfy the condition of 600,000 people collectively traversing its streets.… Read more »

Many rabbonim took on the opinion of Reb Moshe, which is well based and is a legitimate understanding of the sugya (despite the people on this board screaming against it and all of the rabbonim who signed a letter 40 years ago that an eiruv in Brooklyn is impossible) that the entire residential area, as there are no clear dividers, are attachments and extensions of the main street.

The Alter Rebbe spells out the criteria of what is a reshus harabim and based on those conditions its clear that we don’t have a reshus harabim these days.
If you wanted to engineer a city that does have a reshus harabim yes that is possible but not simple.
