Halachot of Eruvim

Why an Eruv:

The Torah requires that Jews not carry any item, no matter its weight or purpose, in a “Reshus HaRabim” (public domain) on Shabbos. When one carries from house to house and from house to street one does an act of society. When one refrains from carrying on Shabbos one pays tribute to G-d. The law on carrying created severe hardships and diminished the oneg (joy) of Shabbos. The Religious court of King Solomon sought to distinguish between a truly public domain where all carrying is prohibited and a more localized domain, bounded by an eruv where not all carrying is prohibited.

For a more philosophical approach to eruvim, read Leora Lawton’s Drash on Eruvim and Tshuvain the honor of the eruv’s fifth anniversary.

What is an Eruv: The Talmud devotes an entire complicated tractate to Eruvin. An Eruv is an enclosure that legally transforms a series of non-connected private domains into a single, unified private-domain. This domain is not determined by a property deal alone but by its symbolic demarcation, or a system of gates.
