An eruv (ערוב, pronounced ay-roov), in modern terminology, is a technical boundary that allows Jews to carry in public areas on Shabbat. It is one of those traditions which has blossomed from a basic Torah principle into a highly complicated legal matter. The eruv has resulted in a growing body of interest throughout the world, and the establishment of organizations to carry it out. There are eruvs ("eruvim" in Hebrew) all the way from Richmond, Virginia, to Gibraltar to Toronto to Melbourne, Australia, to Tel Aviv, and now its coming to Davie.
