Yom Kippur: The Jewish High Holy Fast Day of Atonement

Yom Kippur (Hebrew: יוֹם כִּפּוּר or יום הכיפורים‎, IPA: [ˈjom kiˈpur]), also known as the Day of Atonement, is one of the holiest days of the year for the Jewish people. Its central themes are atonement and repentance.

Jews traditionally observe this holy day with a 25-hour period of fasting and intensive prayer, often spending most of the day in synagogue services. Yom Kippur completes the annual period known in Judaism as the High Holy Days (or sometimes "the Days of Awe"). Boys under the age of 13, and girls under 12, are not required to fast from sundown to sun-up.

Yom Kippur is the tenth day of the month of Tishrei. According to Jewish tradition, God inscribes each person's fate for the coming year into a book, the Book of Life, on Rosh Hashanah, and waits until Yom Kippur to "seal" the verdict. During the Days of Awe, a Jew tries to amend his or her behavior and seek forgiveness for wrongs done against God (bein adam leMakom) and against other human beings (bein adam lechavero). The evening and day of Yom Kippur are set aside for public and private petitions and confessions of guilt (Vidui). At the end of Yom Kippur, one considers oneself absolved by God.

The Yom Kippur prayer service includes several unique aspects. One is the actual number of prayer services. Unlike a regular day, which has three prayer services (Ma'ariv, the evening prayer; Shacharit, the morning prayer; and Mincha, the afternoon prayer), or a Shabbat or Yom Tov, which have four prayer services (Ma'ariv; Shacharit; Musaf, the additional prayer; and Mincha), Yom Kippur has five prayer services (Ma'ariv; Shacharit; Musaf; Mincha; and Ne'ilah, the closing prayer). The prayer services also include a public confession of sins (Vidui) and a unique prayer dedicated to the special Yom Kippur avodah (service) of the Kohen Gadol in the Holy Temple in Jerusalem.

As one of the most culturally significant Jewish holidays, Yom Kippur is observed by many secular Jews who may not observe other holidays. Many secular Jews attend synagogue on Yom Kippur—for many secular Jews the High Holidays are the only recurring times of the year in which they attend synagogue,—causing synagogue attendance to soar, and almost four-fifths fast.

Yom means "day" in Hebrew and Kippur comes from a root that means "to cover or hide"; a secondary meaning is "to obliterate (sin)" and hence "to expiate". Some say there is a link to kapporet, the “mercy seat” or covering of the Ark of the Covenant. Abraham Ibn Ezra holds that the word indicates the task and not just the shape of the ark cover; since the blood of the Yom Kippur sacrifice was sprinkled in its direction (Lev. 16), it was the symbol of propitiation.

Preceding dayErev Yom Kippur (lit. "eve [of] day [of] atonement") is the day preceding Yom Kippur, corresponding to the ninth day of the Hebrew month of Tishrei. This day is commemorated with two festive meals, the giving of charity, and asking others for forgiveness.

Leviticus 16:29 mandates establishment of this holy day on the 10th day of the 7th month as the day of atonement for sins. It calls it the Sabbath of Sabbaths and a day upon which one must afflict one's soul.

Leviticus 23:27 decrees that Yom Kippur is a strict day of rest.

Five additional prohibitions are traditionally observed, as detailed in the Jewish oral tradition (Mishnah tractate Yoma 8:1):

• No eating and drinking
• No wearing of leather shoes
• No bathing or washing
• No anointing oneself with perfumes or lotions
• No marital relations

A parallel has been drawn between these activities and the human condition according to the Biblical account of the expulsion from the garden of Eden. Refraining from these symbolically represents a return to a pristine state, which is the theme of the day.

Total abstention from food and drink usually begins 20 minutes before sundown (called tosefet Yom Kippur, lit. "Addition to Yom Kippur"), and ends after nightfall the following day. Although the fast is required of all healthy adults, it is waived in the case of certain medical conditions.

Virtually all Jewish holidays involve a ritual feast, but since Yom Kippur involves fasting, Jewish law requires one to eat a large and festive meal on the afternoon before Yom Kippur, after the Mincha (afternoon) prayer.

Wearing white clothing, for men a Kittel, is traditional to symbolize one’s purity on this day. Many Orthodox men immerse themselves in a mikvah on the day before Yom Kippur.

Before sunset on Yom Kippur eve, worshippers gather in the synagogue. The Ark is opened and two people take from it two Sifrei Torah (Torah scrolls). Then they take their places, one on each side of the cantor, and the three recite:

In the tribunal of Heaven and the tribunal of earth, by the permission of God—praised be He—and by the permission of this holy congregation, we hold it lawful to pray with transgressors."

The cantor then chants the Kol Nidre prayer (Hebrew: כל נדרי) in Aramaic, not Hebrew. Its name is taken from the opening words, meaning “All vows”:

All personal vows we are likely to make, all personal oaths and pledges we are likely to take between this Yom Kippur and the next Yom Kippur, we publicly renounce. Let them all be relinquished and abandoned, null and void, neither firm nor established. Let our personal vows, pledges and oaths be considered neither vows nor pledges nor oaths.

The leader and the congregation then say together three times “May all the people of Israel be forgiven, including all the strangers who live in their midst, for all the people are in fault.” The Torah scrolls are then replaced, and the Yom Kippur evening service begins.

Many married men wear a kittel, a white robe-like garment for evening prayers on Yom Kippur, otherwise used by males on their wedding day. They also wear a tallit (prayer shawl), which is typically worn on Shabbat and other holidays during morning services.

Prayer services begin with the Kol Nidre prayer, which must be recited before sunset, and continue with the evening prayers (Ma'ariv or Arvith), which includes an extended Selichot service.
The morning prayer service is preceded by litanies and petitions of forgiveness called selichot; on Yom Kippur, many selichot are woven into the liturgy of the mahzor (prayer book). The morning prayers are followed by an added prayer (Musaf) as on all other holidays. This is followed by Mincha (the afternoon prayer) which includes a reading (Haftarah) of the entire Book of Jonah, which has as its theme the story of God's willingness to forgive those who repent.

The service concludes with the Ne'ila ("closing") prayer, which begins shortly before sunset, when the "gates of prayer" will be closed. Yom Kippur comes to an end with a recitation of Shema Yisrael and the blowing of the shofar, which marks the conclusion of the fast.

A recitation of the sacrificial service of the Temple in Jerusalem traditionally features prominently in both the liturgy and the religious thought of the holiday. Specifically, the Avodah (“service”) in the musaf prayer recounts in great detail the sacrificial ceremonies of the Yom Kippur Korbanot (sacrificial offerings) that are recited in the prayers but have not been performed for 2,000 years, since the destruction of the Second Temple in Jerusalem by the Romans.

This traditional prominence is rooted in the Babylonian Talmud’s description of how to attain atonement following the destruction of the Temple. According to Talmud tractate Yoma, in the absence of a Temple, Jews are obligated to study the High Priest’s ritual on Yom Kippur, and this study helps achieve atonement for those who are unable to benefit from its actual performance. In Orthodox Judaism, accordingly, studying the Temple ritual on Yom Kippur represents a positive rabbinically ordained obligation which Jews seeking atonement are required to fulfill.

In Orthodox synagogues, most Conservative, and some progressive, a detailed description of the Temple ritual is recited on the day. In most Orthodox and some Conservative synagogues, the entire congregation prostrates themselves at each point in the recitation where the Kohen Gadol (High Priest) would pronounce the Tetragrammaton (God’s holiest name, according to Judaism), YHWH (I AM THAT AM).

The main section of the Avodah is a threefold recitation of the High Priest’s actions regarding expiation in the Holy of Holies. Performing the sacrificial acts and reciting Leviticus 16:30, (“Your upright children”). (These three times, plus in some congregations the Aleinu prayer during the Musaf Amidah on Yom Kippur and Rosh Hashanah, are the only times in Jewish services when Jews engage in prostration, with the exception of some Yemenite Jews and talmedhei haRambam (disciples of Maimonides) who may prostrate themselves on other occasions during the year). A variety of liturgical poems are added, including a poem recounting the radiance of the countenance of the Kohen Gadol after exiting the Holy of Holies, traditionally believed to emit palpable light in a manner echoing the Torah's account of the countenance of Moses after descending from Mount Sinai, as well as prayers for the speedy rebuilding of the Temple and the restoration of sacrificial worship. There are a variety of other customs, such as hand gestures to mime the sprinkling of blood (one sprinkling upwards and seven downwards per set of eight).

Orthodox liturgies include prayers lamenting the inability to perform the Temple service and petitioning for its restoration, which Conservative synagogues generally omit. In some Conservative synagogues, only the Hazzan (cantor) engages in full prostration. Some Conservative synagogues abridge the recitation of the Avodah service to varying degrees, and some omit it entirely. Many Reform and Reconstructionist services omit the entire service as inconsistent with modernist sensibilities.

The Torah calls the day Yom HaKippurim (יוֹם הַכִּפּוּרִים) and in it Leviticus 23:27 decrees a strict prohibition of work and affliction of the soul upon the tenth day of the seventh month, later known as Tishrei. The rites for Yom Kippur are set forth in Leviticus 16:1-34 (cf. Exodus 30:10; Leviticus 23:27-32, Leviticus 25:9; Numbers 29:7-11.)

  

Traditionally, Yom Kippur is considered the date on which Moses received the second set of Ten Commandments. It occurred following the completion of the second 40 days of instructions from God. At this same time, the Israelites were granted atonement for the sin of the Golden Calf; hence, its designation as the Day of Atonement.

The following summary of the Temple service is based on the traditional Jewish religious account described in Mishnah tractate Yoma, appearing in contemporary traditional Jewish prayerbooks for Yom Kippur, and studied as part of a traditional Jewish Yom Kippur worship service.

While the Temple in Jerusalem was standing (from Biblical times through 70 A.D.), the Kohen Gadol (High Priest) was mandated by the Torah to perform a complex set of special services and sacrifices for Yom Kippur to attain Divine atonement, the word "kippur" meaning "atone" in Hebrew. These services were considered to be the most important parts of Yom Kippur because through them the Kohen Gadol made atonement for all Jews and the world. During the service, the Kohen Gadol entered the Holy of Holies in the center of the Temple, the only time of the year that anyone went inside. Doing so required special purification and preparation, including five immersions in a mikvah (ritual bath), and four changes of clothing.

Seven days prior to Yom Kippur, the Kohen Gadol was sequestered in the Palhedrin chamber in the Temple, where he reviewed (studied) the service with the sages familiar with the Temple, and was sprinkled with spring water containing ashes of the Red Heifer as purification. The Talmud (Tractate Yoma) also reports that he practiced the incense offering ritual in the Avitnas chamber.

On the day of Yom Kippur, the Kohen Gadol had to follow a precise order of services, sacrifices, and purifications:

• Morning (Tamid) Offering The Kohen Gadol first performed the regular daily (Tamid) offering — usually performed by ordinary priests — in special golden garments, after immersing in a mikvah and washing his hands and feet.
• Garment Change 1 The Kohen Gadol immersed in a special mikvah in the Temple courtyard and changed into special linen garments, and washed his hands and feet twice, once after removing the golden garments and once before putting on the linen garments.
• Bull as Personal Sin-Offering The Kohen Gadol leaned (performed Semikha) and made a confession over the bull on behalf of himself and his household, pronouncing the Tetragrammaton. The people prostrated themselves when they heard. He then slaughtered the bull as a chatat (sin-offering) and received its blood in a bowl.
• Lottery of the goats At the Eastern (Nikanor) gate, the Kohen Gadol drew lots from a lottery box over two goats. One was selected “for the Lord,” and one “for Azazel.” The Kohen Gadol tied a red band around the horns of the goat “for Azazel.”
• Incense Preparation The Kohen Gadol ascended the mizbeach (altar) and took a shovel full of embers with a special shovel. He was brought incense. He filled his hands and placed it in a vessel. (The Talmud considered this the most physically difficult part of the service, as the Kohen Gadol had to keep the shovelful of glowing coals balanced and prevent its contents from dropping, using his armpit or teeth, while filling his hands with the incense).
• Incense Offering Holding the shovel and the vessel, he entered the Kadosh Hakadashim, the Temple’s Holy of Holies. In the days of the First Temple, he placed the shovel between the poles of the Ark of the Covenant. In the days of the Second Temple, he put the shovel where the Ark would have been. He waited until the chamber filled with smoke and left.
• Sprinkling of Bull's Blood in the Holy of Holies The Kohen Gadol took the bowl with the bull’s blood and entered the Most Holy Place again. He sprinkled the bull’s blood with his finger eight times, before the Ark in the days of the First Temple, where it would have been in the days of the Second. The Kohen Gadol then left the Holy of Holies, putting the bowl on a stand in front of the Parochet (curtain separating the Holy from the Holy of Holies).
• Goat for the Lord as Sin-Offering for Kohanim The Kohen Gadol went to the eastern end of the Israelite courtyard near the Nikanor Gate, laid his hands (semikha) on the goat “for the Lord,” and pronounced confession on behalf of the Kohanim (priests). The people prostrated themselves when he pronounced the Tetragrammaton. He then slaughtered the goat, and received its blood in another bowl.
• Sprinkling of Goat’s Blood in the Holy of Holies The Kohen Gadol took the bowl with the goat’s blood and entered the Kadosh Hakadashim, the Temple’s Holy of Holies again. He sprinkled the goat’s blood with his finger eight times the same way he had sprinkled the bull’s blood. The blood was sprinkled before the Ark in the days of the First Temple, where it would have been in the days of the Second Temple. The Kohen Gadol then left the Kadosh Hakadashim, putting the bowl on a stand in front of the Parochet (curtain separating the Holy from the Holy of Holies).
• Sprinkling of blood in the Holy Standing in the Hekhal (Holy), on the other side of the Parochet from the Holy of Holies, the Kohen Gadol took the bull's blood from the stand and sprinkled it with his finger eight times in the direction of the Parochet. He then took the bowl with the goat's blood and sprinkled it eight times in the same manner, putting it back on the stand.
• Smearing of blood on the Golden (Incense) Altar The Kohen Gadol removed the goat’s blood from the stand and mixed it with the bull's blood. Starting at the northeast corner, he then smeared the mixture of blood on each of the four corners of the Golden (Incense) altar in the Haichal. He then sprinkled the blood eight times on the altar.
• Goat for Azazel The Kohen Gadol left the Haichal and walked to the east side of the Azarah (Israelite courtyard). Near the Nikanor Gate, he leaned his hands (Semikha) on the goat “for Azazel” and confessed the sins of the entire people of Israel. The people prostrated themselves when he pronounced the Tetragrammaton. While he made a general confession, individuals in the crowd at the Temple would confess privately. The Kohen Gadol then sent the goat off “to the wilderness.” In practice, to prevent its return to human habitation, the goat was led to a cliff outside Jerusalem and pushed off its edge.
• Preparation of sacrificial animals While the goat “for Azazel” was being led to the cliff, the Kohen Gadol removed the insides of the bull, and intertwined the bodies of the bull and goat. Other people took the bodies to the Beit HaDeshen (place of the ashes). They were burned there after it was confirmed that the goat “for Azazel” had reached the wilderness.
• Reading the Torah After it was confirmed that the goat “for Azazel” had been pushed off the cliff, the Kohen Gadol passed through the Nikanor Gate into the Ezrat Nashim (Women’s Courtyard) and read sections of the Torah describing Yom Kippur and its sacrifices.
• Garment change 2 The Kohen Gadol removed his linen garments, immersed in the mikvah in the Temple courtyard, and changed into a second set of special golden garments. He washed his hands and feet both before removing the linen garments and after putting on the golden ones.
• Offering of Rams The Kohen Gadol offered two rams as an olah offering, slaughtering them on the north side of the mizbeach (outer altar), receiving their blood in a bowl, carrying the bowl to the outer altar, and dashing the blood on the northeast and southwest corners of the Outer Altar. He dismembered the rams and burned the parts entirely on the outer altar. He then offered the accompanying mincha (grain) offerings and nesachim (wine-libations).
• Musaf Offering The Kohen Gadol then offered the Musaf offering.
• Burning of Innards The Kohen Gadol placed the insides of the bull and goat on the outer altar and burned them entirely.
• Garment change 3 The Kohen Gadol removed his golden garments, immersed in the mikvah, and changed to a new set of linen garments, again washing his hands and feet twice.
• Removal of Incense from the Holy of Holies The Kohen Gadol returned to the Holy of Holies and removed the bowl of incense and the shovel.
• Garment Change 4 The Kohen Gadol removed his linen garments, immersed in the mikvah, and changed into a third set of golden garments, again washing his hands and feet twice.
• Evening (Tamid) Offering The Kohen Gadol completed the afternoon portion of the regular (tamid) daily offering in the special golden garments. He washed his hands and feet a tenth time.

The Kohen Gadol wore five sets of garments (three golden and two white linen), immersed in the mikvah five times, and washed his hands and feet ten times. Sacrifices included two (daily) lambs, one bull, two goats, and two rams, with accompanying mincha (meal) offerings, wine libations, and three incense offerings (the regular two daily and an additional one for Yom Kippur). The Kohen Gadol entered the Holy of Holies three times. The Tetragrammaton was pronounced three times, once for each confession.
