After liberation from slavery in Egypt, our ancestors wandered in the desert for forty years and lived in temporary dwellings. Sukkot, or the Feast of Booth is a seven-day long holiday, commemorating the Exodus. As a most important practical rule, a sukkah or booth is to be built and a bouquet consisting of four plants needs to be obtained. Traditionally, the building of the sukkah commenced after Yom Kippur to serve for many as a temporary dwelling throughout the holiday of Sukkot. Others only ate meals in the sukkah, constructed either in the courtyard of synagogues or, less frequently, in their own gardens. According to rabbinical traditions, on each day of the holiday, special guests (ushpizin) also arrive to the sukkah: Abraham, Isaac, Jacob, Joseph, Moses, Aaron and David each visit the sukkah.
