Jewish Holiday & Shabbat Prayers
No matter what the Jewish holiday is, you can depend upon the worship service lasting longer than its weekday counterpart! This is because each and every holiday in the Jewish calendar comes with its own unique set of insertions into the prayers intended to celebrate the special character of that festival. The same is true of the Shabbat services, which have special insertions turning every Saturday into a holiday as well. There is a predictable and regular structure of the holiday and Shabbat prayers.
First and foremost, the middle portion of every Amidah--or "standing" prayer, the central prayer of Jewish services--is different depending upon the day. In each Shabbat Amidah, we recite biblical verses or poetry about Shabbat, thanking God for the gift of a day of rest. On Passover, we thank God for the holiday of "our redemption" from Egypt; on Shavuot for the "giving of our Torah" at Mt. Sinai; and on Sukkot for the "season of our joy." The central blessing of each festival Amidah thanks God for the gift of the season and for sanctifying the people of Israel with these holidays.
Rosh Hashanah and Yom Kippur, although somewhat more somber festivals, also include additions thanking God for these holidays. Only Hanukkah and Purim lack these inclusions. Instead, they have special additions in the regular Amidah thanking God for the miracles and redemptive acts that God wrought for the Jewish people in ancient times.
The three pilgrimage festivals, Shemini Atzeret, Hanukkah, and Rosh Chodesh are also characterized by the joyous singing and recitation of a group of Psalms called Hallel, meaning "praise." Beginning with Psalm 113 and concluding with Psalm 118, the theme of Hallel is gratitude to God. Some Jews have added Hallel to their celebration of Yom Ha-Atzma'ut (Israel Independence Day). An abbreviated version of Hallel is recited on Rosh Chodesh and the last six days of Passover.
Some holidays are also characterized by the chanting of one of the five megillot, or biblical scrolls, which further emphasize the character of the festival. Song of Songs, which is a celebration of young love, is chanted on Passover in the spring; Ruth, a story about a convert's accepting the Torah, is chanted on Shavuot, which celebrates the assumption of the Torah on behalf of the whole people of Israel; and Ecclesiastes (Kohelet), which deals with the cyclical nature of all life, is chanted on Sukkot in the autumn. Purim, of course, is celebrated by the raucous chanting of the scroll of Esther (Megillat Esther).
Every Shabbat, a portion of the Torah is read in seven parts (aliyot), as well as a corresponding Haftarah (prophetic) reading. Each holiday has special Torah and Haftarah readings, and the three pilgrimage festivals and Yom Kippur add a special addition to the service called Yizkor. Yizkor is a semi-regular opportunity for congregants to recall their departed loved ones.
