In Temple times, all males were required to appear at the Temple three times annually and actively participate in the festal offerings and celebrations. These were the joyous pilgrim festivals of Pesach, Shavuot, and Sukkot. Originally, they marked the major agricultural seasons in ancient Israel and commemorated Israel’s early history; but after the destruction of the Second Temple in 70 ce, emphasis was almost exclusively placed on the commemorative aspect.

In modern Israel, Pesach, Shavuot, and Sukkot are celebrated for the number of days prescribed by Scripture, namely, seven days, one day, and eight days, respectively (with Shemini Atzeret added to Sukkot). Due to calendrical uncertainties which arose in Second Temple times (6th century bce to 1st century ce), each festival is celebrated for an additional day in the Diaspora.

Pesach commemorates the Exodus from Egypt and the servitude that preceded it. As such, it is the most significant of the commemorative holidays, for it celebrates the very inception of the Jewish people—i.e., the event which provided the basis for the covenant between God and Israel. The term pesaḥ refers originally to the paschal (Passover) lamb sacrificed on the eve of the Exodus, the blood of which marked the Jewish homes to be spared from God’s plague; its etymological significance, however, remains uncertain. The Hebrew root is usually rendered “passed over”—i.e., God passed over the homes of the Israelites when inflicting the last plague on the Egyptians—hence the term Passover. The festival is also called Ḥag Matzot (“Festival of Unleavened Bread”), for unleavened bread is the only kind of bread consumed during Passover.

Leaven (seʾor) and foods containing leaven (ḥametz) are neither to be owned nor consumed during Pesach. Aside from meats, fresh fruits, and vegetables, it is customary to consume only those foods prepared under rabbinic supervision and labelled “kosher for Passover,” warranting that they are completely free of contact with leaven. In many homes, special sets of crockery, cutlery, and cooking utensils are acquired for Passover use. On the evening preceding the 14th day of Nisan, the home is thoroughly searched for any trace of leaven (bediqat ḥametz). The following morning the remaining particles of leaven are destroyed by fire (biʿur ḥametz). From then until after Pesach, no leaven is consumed. Many Jews sell their more valuable leaven products to non-Jews before Passover (mekhirat ḥametz), repurchasing the foodstuffs immediately after the holiday.

The unleavened bread (matza) consists entirely of flour and water, great care being taken to prevent any fermentation before baking. Hand-baked matza is flat, rounded, and perforated. Since the 19th century, many Jews have preferred the square-shaped, machine-made matza.

Passover eve is ushered in at the synagogue service on the evening before Passover, after which each family partakes of the seder (“order of service); i.e., an elaborate festival meal in which every ritual is regulated by the rabbis. (In the Diaspora, the seder is also celebrated on the second evening of Passover.) The table is bedecked with an assortment of foods symbolizing the passage from slavery (e.g., bitter herbs) into freedom (e.g., wine). The Haggada (literally “narration”), a printed manual comprised of appropriate passages culled from Scripture, Talmud, and Midrash, accompanied by medieval hymns, serves as a guide for the ensuing ceremonies and is recited as the evening proceeds. The seder opens with the cup of sanctification (Qiddush), the first of four cups of wine drunk by the celebrants. An invitation is extended to the needy to join the seder ceremonies, after which the youngest son asks four prescribed questions expressing his surprise at the many departures from usual mealtime procedure. (“How different this night is from all other nights!”) The father then explains that the Jews were once slaves in Egypt, were then liberated by God, and now commemorate the servitude and freedom by means of the seder ceremonies. Special blessings are recited over the unleavened bread and the bitter herbs (maror), after which the main courses are served. The meal closes with a serving of matza recalling the paschal lamb, consumption of which concluded the meal in Temple times. The seder concludes with the joyous recital of hymns praising God’s glorious acts in history and anticipating a messianic redemption to come.

The Passover liturgy is considerably expanded and includes the daily recitation of Psalms 113–118 (Hallel, “praise”), public readings from the Torah, and an additional service (musaf). On the first day of Pesach, a prayer for dew in the Holy Land is recited; on the last day, the memorial service for the departed (yizkor) is added.

Originally an agricultural festival marking the wheat harvest, Shavuot commemorates the revelation of the Torah at Sinai. Shavuot (“weeks”) takes its name from the seven weeks of grain harvest separating Passover and Shavuot. The festival is also called Ḥag ha-Qazir (Harvest Festival) and Yom ha-Bikkurim (Day of First Fruits). Greek-speaking Jews called it pentēkostē, meaning “the fiftieth” day after the sheaf offering. In rabbinic literature, Shavuot is called atzeret (“cessation, conclusion”), perhaps because the cessation of work is one of its distinctive features, or possibly because it was viewed as concluding the Passover season. In liturgical texts it is described as the “season of the giving of our Torah.” The association of Shavuot with the revelation at Sinai, while not attested to in Scripture, is alluded to in the Pseudepigrapha (a collection of noncanonical writings). In rabbinic literature the association first appears in 2nd-century materials. The association, probably an ancient one, was derived in part from the book of Exodus, which dates the revelation at Sinai to the third month (counting from Nisan), i.e., Sivan.

Scripture does not provide an absolute date for Shavuot. Instead, 50 days (or seven weeks) are reckoned from the day the sheaf offering (ʿOmer) of the harvest was brought to the Temple, the 50th day being Shavuot. According to the Talmudic rabbis, the sheaf offering was brought on the 16th of Nisan; hence Shavuot always fell on or about the 6th of Sivan. Jewish sectarians, such as the Sadducees, rejected the rabbinic tradition concerning the date of the sheaf ceremony, preferring a later date, and celebrated Shavuot accordingly.

In Temple times, aside from the daily offerings, festival offerings, and first-fruit gifts, a special cereal offering consisting of two breads prepared from the new wheat crop was offered at the Temple. Since the destruction of the Second Temple, Shavuot observances have been dominated by its commemorative aspect. Many Jews spend the entire Shavuot night studying Torah, a custom first mentioned in the Zohar (“Book of Splendour”), a Kabbalistic work edited and published in the 13th–14th centuries. Some prefer to recite the tiqqun lel Shavuʿot (“Shavuot night service”), an anthology of passages from Scripture and the Oral Law (Mishna) compiled in the late medieval period. An expanded liturgy includes Hallel, public readings from the Torah, yizkor (in many congregations), and musaf. The Book of Ruth is read at the synagogue service, possibly because of its harvest-season setting.

Sukkot (“booths”), an ancient harvest festival that commemorates the booths the Israelites resided in after the Exodus, was the most prominent of the three pilgrim festivals in ancient Israel. Also called Ḥag ha-Asif (Festival of Ingathering), it has retained its joyous, festive character through the ages. It begins on Tishri 15 and is celebrated for seven days. The concluding eighth day (plus a ninth day in the Diaspora), Shemini Atzeret, is a separate holiday. In Temple times, each day of Sukkot had its own prescribed number of sacrificial offerings. Other observances, recorded in the Mishna tractate Sukka, include the daily recitation of Hallel, daily circumambulation of the Temple altar, a daily water libation ceremony, and the nightly bet ha-shoʾeva or bet ha-sheʾuvah (“place of water drawing”) festivities starting on the evening preceding the second day. The last mentioned featured torch dancing, flute playing, and other forms of musical and choral entertainment.

Ideally, Jews are to reside in booths—walled structures covered with thatched roofs—for the duration of the festival; in practice, most observant Jews take their meals in the sukka (“booth”) but reside at home. A palm-tree branch (lulav), bound up together with myrtle (hadas) and willow (ʿarava) branches, is held together with a citron (etrog) and waved. Medieval exegetes provided ample (if not always persuasive) justification for the Bible’s choice of these particular branches and fruit as symbols of rejoicing. The numerous regulations governing the sukka, lulav, and etrog comprise the major portion of the treatment of Sukkot in the codes of Jewish law. The daily Sukkot liturgy includes the recitation of Hallel, public readings from the Torah, the musaf service, and the circumambulation of the synagogue dais. On the last day of Sukkot, called Hoshana Rabba (Great Hoshana) after the first words of a prayer (hoshana, “save us”) recited then, seven such circumambulations take place. Kabbalistic (mystical) teaching has virtually transformed Hoshana Rabba into a solemn day of judgment.

Hoshana Rabba is followed by Shemini Atzeret (Eighth Day of Solemn Assembly), which is celebrated on Tishri 22 (in the Diaspora also Tishri 23). None of the more distinctive Sukkot observances apply to Shemini Atzeret; but Hallel, public reading from the Torah, yizkor (in many congregations), musaf, and a prayer for rain in the Holy Land are included in its liturgy. Simchat Torah (Rejoicing of the Law) marks the annual completion of the cycle of public readings from the Torah. The festival originated shortly before the gaonic period (c. 600–1050 ce) in Babylon, where it was customary to conclude the public readings annually. In Palestine, where the public readings were concluded approximately every three years, Simchat Torah was not celebrated annually until after the gaonic period. Israeli Jews celebrate Simchat Torah and Shemini Atzeret on the same day; in the Diaspora, Simchat Torah is celebrated on the second day of Shemini Atzeret. Its joyous celebrations bring the Sukkot season to an appropriate close.
