Yom Kippur Temple service

In Judaism, the Yom Kippur Temple service was a special sacrificial service performed by the High Priest of Israel on the holiday of Yom Kippur, in the Temple in Jerusalem (and previously in the Tabernacle). Through this service, according to the Bible, the Jewish people would achieve atonement for their sins once each year. The service is notable as the only time in the year any person was allowed to enter the Holy of Holies, and is the source of the term scapegoat.

The service is commanded in Leviticus 16, and its laws are discussed in the Mishnah and Talmud in tractate Yoma.
