This sacred Day took place in September-October, six months after the Passover. According to the Jewish calendar, it came on the tenth day of the seventh month (Lev.16:29; 23:26-32; Num.29:7-11), and occurred, “year by year.” The Day of Atonement was instituted by Moses as part of a comprehensive system of sacrifice which centred on Israel’s faith in one God whose name was LORD/Jehovah/Yahweh (Deut.6:4) and provided complete atonement for all, including the High Priest and his family and every person and family in Israel.
