The Festival of Trumpets begins ten days of preparation for Yom Kippur, a title that means “Day of Atonement.” It is the appointed time of the tenth day of the seventh month. It is a fast day—a day for confessing sins, repenting, and asking God for forgiveness. In the days of the Tabernacle and Temple, as discussed in Leviticus 16, it was a day of solemn sacrificial rituals for purification and atonement. It was the only day of the year when the high priest was allowed to enter the holy of holies.
