Editing Yom Kippur (section)

== In the Torah ==
The [[Torah]] calls the day {{Lang|hbo-latn|Yom HaKippurim}} ({{Lang|hbo|{{Script|Hebrew|יוֹם הַכִּיפּוּרִים}}|rtl=yes}}), and decrees fasting ("affliction of the soul") and a strict prohibition of work on the tenth day of the seventh month, later known as [[Tishrei]].<ref name="bibleverse||Leviticus|23:27|HE">{{bibleverse||Leviticus|23:27|HE}}</ref> The laws of Yom Kippur are commanded by God to Moses in three passages in the Torah:
# {{Bibleverse|Leviticus|16:1–34|HE}}: [[Aaron]] may only enter the sanctuary by performing a complex sacrificial procedure, later known as the [[Yom Kippur Temple service]]. This service must be performed yearly on the date of Yom Kippur, while the people are to fast and not work on this date.<ref>{{bibleverse||Leviticus|16:1–34|HE}}</ref>
# {{Bibleverse|Leviticus|23:26–32|HE}}: The tenth day of Tishrei is a holy day of atonement. A Temple sacrifice must be offered, while the people must fast and not work, "on the ninth day from evening until evening".<ref>{{bibleverse||Leviticus|23:26–32|HE}}</ref>
# {{Bibleverse|Numbers|29:7–11|HE}}: The tenth day of Tishrei is a holy day; one must fast and not work. The ''[[mussaf]]'' (additional) sacrifice for the day is specified.<ref>{{bibleverse||Numbers|29:7–11|HE}}</ref>

Yom Kippur is mentioned briefly in another context: on Yom Kippur of the [[Jubilee (biblical)|Jubilee year]] the [[shofar]] was to be blown.<ref>{{Bibleverse|Leviticus|25:9|HE}}</ref> According to some, this is the source for the current custom of blowing the shofar at the conclusion of Yom Kippur.<ref>[[Jacob ben Judah Landau|Sefer Haagur]], Hilchot Yom Hakippurim 951: ...ותוקעין תקיעה אחת זכר ליובל</ref>

=== Temple service ===
{{Main|Yom Kippur Temple service}}

When the [[Temple in Jerusalem]] stood, Yom Kippur was the occasion of an elaborate sacrificial service, as commanded by {{Bibleverse|Leviticus|16|HE}}. The rabbis summarized the laws of this service in [[Mishnah]] tractate [[Yoma]], and they appear in contemporary traditional Jewish prayer books for Yom Kippur, and are studied as part of a traditional Jewish Yom Kippur worship service.<ref name=kasirer>Arnold Lustiger, Michael Taubes, [[Menachem Genack]], and [[Hershel Schachter]], ''Kasirer Edition Yom Kippur Machzor With Commentary Adapted from the Teachings of Rabbi [[Joseph B. Soloveitchik]]''.
