In Jewish religious property law, an Eruv is a legal aggregation or "mixture" of separate parcels of property. Under certain conditions these mixed properties may be considered a single entity held in common by all the holders of the original parcels. As a result, certain actions, which might otherwise be prohibited on the Sabbath, such as carrying from one parcel to another, are permitted. Eruvin (mixtures) is the second tractate of the order Mo'ed and deals with all aspects of the Sabbath eruv. It is thus a continuation of the tractate Shabbat, and in fact, it appears that originally the two tractates were combined, but considering that such a combined tractate would have comprised 34 chapters, an inordinately lengthy and unwieldy amount, the tractate was divided into two separate units.
