27 "Be careful to celebrate the Day of Atonement on the tenth day of that same month-nine days after the Festival of Trumpets. You must observe it as an official day for holy assembly, a day to deny yourselves and present special gifts to the Lord . 28 Do no work during that entire day because it is the Day of Atonement, when offerings of purification are made for you, making you right with the Lord your God. 29 All who do not deny themselves that day will be cut off from God's people. 30 And I will destroy anyone among you who does any work on that day. 31 You must not do any work at all! This is a permanent law for you, and it must be observed from generation to generation wherever you live. 32 This will be a Sabbath day of complete rest for you, and on that day you must deny yourselves. This day of rest will begin at sundown on the ninth day of the month and extend until sundown on the tenth day."

Commentary on Leviticus 23:23-32
(Read Leviticus 23:23-32)
the blowing of trumpets represented the preaching of the gospel, by which men are called to repent of sin, and to accept the salvation of Christ, which was signified by the day of atonement. Also it invited to rejoice in God, and become strangers and pilgrims on earth, which was denoted by the feast of Tabernacles, observed in the same month. At the beginning of the year, they were called by this sound of trumpet to shake off spiritual drowsiness, to search and try their ways, and to amend them. The day of atonement was the ninth day after this; thus they were awakened to prepare for that day, by sincere and serious repentance, that it might indeed be to them a day of atonement. The humbling of our souls for sin, and the making our peace with God, is work that requires the whole man, and the closest application of mind. On that day God spake peace to his people, and to his saints; therefore they must lay aside all their wordly business, that they might the more clearly hear that voice of joy and gladness.
