An annual day of fasting and prayer among the Israelites, still observed by their descendants, the present-day Jews. It occurs in autumn, and its observance is one of the requirements of the Mosaic law. Jews call this day Yom Kippur.
the great annual day of humiliation and expiation for the sins of the nation, "the fast" (Acts 27:9), and the only one commanded in the law of Moses. The mode of its observance is described in Lev. 16:3-10; 23:26-32; and Num. 29:7-11. It was kept on the tenth day of the month Tisri, i.e., five days before the feast of Tabernacles, and lasted from sunset to sunset. (See AZAZEL.)
