Feast of Trumpets/Yom Teruah:
The beginning of the fall festival season and the final harvest of ingathering is heralded by the blowing of trumpets. This Holy Day has multiple historic and prophetic meanings. This holy time is the beginning of the ten days of national repentance and reconciliation called the Days of Awe that are completed on the Day of Atonement. It begins the 15 day ascent to Jerusalem, memorialized in the Psalms of Ascent, as the people journeyed up to Jerusalem to celebrate the Feast of Tabernacles (Succoth). And it looks forward to the coming of the Messiah, to destroy those who destroy the earth and to bring peace and justice to all who look longingly for His return.
Then the Lord spoke to Moses, saying, 24 “Speak to the children of Israel, saying: ‘In the seventh month, on the first day of the month, you shall have a sabbath-rest, a memorial of blowing of trumpets, a holy convocation. 25 You shall do no customary work on it; and you shall offer an offering made by fire to the Lord.’” Leviticus 23
