The Hebrew Bible calls it  “Chag HaSukkot,” “Festival of the Booths” (Leviticus 23:34-36). This Festival is concluded after eight days, known in Hebrew as Shemini Atzeret. God commanded His people to build booths and live in these temporary dwellings during Sukkot to remind us of our humble beginnings in the wilderness.  “You shall dwell in booths for seven days”  (Leviticus 23:42-43).
