History of Yom Kippur: Day of Atonement
The Jewish High Holy Days begin with Rosh Hashanah and continue until Yom Kippur. Yom Kippur, the “Day of Atonement,” or more correctly Yom ha-Kippurim (Leviticus 16), goes back to Jewish antiquity almost 4,000 years to the time of Moses. This most solemn occasion of the Jewish Festival cycle was the season for annual cleansing from sin, but in time its significance was deepened so that it acquired personal meaning and filled a personal need. It is observed on the 10th day of Tishri, the seventh month, and is the climax of the whole penitential season.
Yom Kippur in Biblical Times
Originally, on one day of the year, the high priest would enter into the innermost part of the Tabernacle (and later the Temple in Jerusalem). He would enter the Holy of Holies with the blood of the sacrifice for the sin of the people as a congregation and sprinkle it upon the ‘mercy seat’ of the Ark of the Covenant (made famous by the movie “Raiders of the Lost Ark” :-). This would “cover” the sin of the people, as this is what the Aramaic (and Hebrew) root “kaphar” (atonement) means. With the destruction of the Temple in 70 A.D., later Rabbinic legislation adapted the old ritual to the synagogue. The blast of the ‘shofar,’ the ritual ram’s horn trumpet, signifies, among other things, the inarticulate cry of the soul to God.
