Origin and Meaning of Yom Kippur
Yom Kippur, meaning "Day of Atonement" in Hebrew, is the holiest day of the Jewish year, sometimes called the "Sabbath of Sabbaths." According to Jewish tradition, the first Yom Kippur occurred after the Israelites' exodus from Egypt and arrival at Mount Sinai, following the golden calf incident. During biblical times, Yom Kippur was the only day the high priest could enter the inner sanctum of the Holy Temple in Jerusalem to perform atonement rituals and sprinkle sacrificial animal blood on the Ark of the Covenant. This temple tradition continued until the Roman destruction of the Second Temple in 70 A.D., after which observance adapted into synagogue services led by rabbis and congregations.
Yom Kippur falls during the 10 Days of Awe between Rosh Hashanah and Yom Kippur itself, when Jewish tradition holds that God judges all creatures and inscribes names in the "book of life." The day is devoted to seeking forgiveness from God and fellow humans through private introspection combined with communal observance. The concept of "teshuvah" (repentance) is central to the observance, with observant Jews using this period for prayer, good deeds, reflection on mistakes, and making amends with others.
Fasting and Physical Observances
Yom Kippur lasts approximately 25 hours, beginning half an hour before sundown and ending after nightfall the following evening. The most distinctive practice is a complete fast from food and drink. Jewish adults—excluding the sick, elderly, pregnant women, recently postpartum women, young children, and those with medical conditions—abstain from eating and drinking for this entire period.
Beyond fasting, observant Jews observe additional restrictions intended to prevent focus on material possessions and superficial comforts:
- Bathing or washing
- Using cosmetics
- Wearing leather shoes
- Sexual relations
- Work of any kind
Many observant Jews wear white clothing to symbolize purity and renewal. Some married men wear kittels, white burial shrouds, to signify repentance and humility.
Religious Services and Prayers
Five distinct prayer services occur on Yom Kippur, beginning on the eve before and concluding before sunset. Services use a special prayer book called the machzor. The observance begins with the Kol Nidrei service, a centuries-old Aramaic prayer recited by the prayer leader flanked by two witnesses holding Torahs, simulating a Jewish court or beit din.
Throughout the day, confessional statements are recited in plural form, emphasizing collective responsibility rather than individual guilt alone. Some communities incorporate singing and dancing during services. The final service concludes with a single long blast of the shofar (ram's horn trumpet), marking the end of the fast. Many communities conclude with the declaration "L'shana Haba'ah B'Yerushalayim" (Next Year in Jerusalem).
Customs and Celebrations
Yom Kippur observance combines solemn introspection with hopeful renewal. Key customs include:
- Pre-fast feast: Families gather for a substantial meal before sunset on Yom Kippur Eve to prepare for the coming fast
- Breaking the fast: After final services, people share festive meals with comfort foods like blintzes and noodle pudding
- Charity: Donations and volunteering occur during the Days of Awe, with those who fast often giving to the poor
- Kapparot: An ancient custom involving circling a live chicken or coins overhead while reciting prayers, then giving the monetary equivalent to the poor
The fast is understood as a spiritual practice intended to cleanse body and spirit, not as punishment or a practice meant to cause harm. Even non-observant Jews typically refrain from work and attend synagogue services on this day. Synagogue attendance surges significantly during Yom Kippur, with some congregations renting additional space for worshippers who wish to participate in the communal observance.
