Yom Kippur is one of the most widely observed holidays on the Jewish calendar.
It marks the highest synagogue attendance rate of any other day in the year. Despite its widespread observance and long hours spent in synagogue, Yom Kippur is a difficult day to understand.
The major theme of Yom Kippur, as its name implies, is atonement. The source for much of our observance of Yom Kippur is Leviticus 23:26-28 – “God spoke to Moses, saying: Mark, the tenth day of this seventh month is the Day of Atonement. It shall be a sacred occasion for you: you shall practice self-denial, and you shall do no work throughout that day for it is a Day of Atonement, on which expiation is made on your behalf before the Lord your God.”
