Atonement, Day of

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; Lev 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.)
