The Torah insistently connects the festival of Sukkot with the obligation to rejoice (once in this week's parashah), and later Jewish tradition calls Sukkot z'man simhateinu, the time of our joy. Why is Sukkot of all holidays singled out as the time of happiness and delight? Understanding the joy associated with Sukkot helps us gain crucial insight into the nature and dynamics of God's covenant with the Jewish people.
