(My Jewish Learning) The status of Shemini Atzeret can be confusing at first glance. Its name means the “eighth day of assembly” — which would imply that it somehow belongs to the seven-day holiday that immediately precedes it, Sukkot.
In Numbers 29:35 we learn that “On the eighth day you should hold a solemn gathering; you shall not work at your occupation.” This verse does not connect the eighth day specifically to any of the other traditions associated with Sukkot, begging the question: Is this its own distinct holiday or part of Sukkot? Shemini Atzeret serves to conclude the holiday of Sukkot , although it technically stands as its own festival. In this way Sukkot begins with a yom tov (full holiday) and ends with a yom tov, while the days in between are the intermediate festival days (hol ha-mo’ed). Thus, the concluding holiday acts as a transitional day leading the worshipper out of the various levels of meaning inherent in Sukkot. In his book The Jewish Holidays, Michael Strassfeld points out that Shemini Atzeret in many respects parallels Shavuot, which can be viewed as the long-distance conclusion to the seven-day holiday of Passover, coming as it does seven weeks after Passover. At that time of year, the weather would be clear enough to have people come back to Jerusalem for an additional pilgrimage some weeks later. Sukkot, however, marks the beginning of the rainy season, and since it would be difficult to ask people to make an additional trip to Jerusalem, Shemini Atzeret would best be placed immediately following Sukkot. The Rabbis say that the festival is God’s way to retain closeness with the Jewish people for a little while longer.
Shemini Atzeret is a two-day festival in traditional communities outside the land of Israel and a one-day holiday in Israel and in many liberal communities. The only ritual that is unique to Shemini Atzeret is the prayer for rain (tefilat geshem), and this prayer is parallel to the prayer for dew which is recited on Passover. These two holidays serve as the bookends of the agricultural season, at the beginning and end of the rainy season.
In the early Middle Ages, Shemini Atzeret began to be associated with the ritual of completing the yearly cycle of readings from the Torah , leading to the later development of Simchat Torah. Simchat Torah developed into the day on which we celebrate the ending of one cycle of Torah reading and the beginning of the next cycle.
It is a joyous holiday with a relatively young history, since it is not mentioned in the Torah. It is traditionally the only time when the Torah is read at night, when we read the last section from Deuteronomy, to be followed the next day by the beginning of Genesis. There is a tradition on Simchat Torah morning of calling all members of the community to say the blessing over the Torah, known as an aliyah, and synagogues will often repeat the reading until all members have had their aliyot (plural).
Similar to Sukkot, there are several circuits around the synagogue on Simchat Torah. These are known as hakafot (singular: hakafah). In distinction to the hakafot on Sukkot, they are done holding the Torah, not the lulav and etrog. They are accompanied by joyous dancing that often spills onto the street outside.
In Kabbalah (the mystical tradition) the seven hakafot on Simhat Torah became a kind of unification of the seven days of Sukkot and also representative of the seven sephirot (emanations of God). This spiritual and mystical understanding of Simchat Torah accords with the very physical tradition of turning the hakafot into joyous dancing. The Torah reading that follows the wild dancing is often very playful and humorous, as it is a celebration of the great gift of God’s Torah.
In recent times, Simchat Torah has also become a very “child-friendly” holiday. Many synagogues invite all the children up for a group aliyah and give out flags for the children to march around with during their own hakafah.
While Simchat Torah’s origins are not specifically biblical, it has become a Bible-centered holiday on which the hearts of Jews are drawn to celebrate the Torah.
