Why were trumpets used in the Bible?

This Teaching examines the Feast of Trumpets (Yom Teruah) by beginning with the written commands and then tracing the biblical use of trumpets, shouts, remembrance, gathering, and the return of Yeshua. It opens with Ezra’s example of seeking, doing, and teaching the Law of Yehovah and Matthew 5’s emphasis on doing and teaching the commandments. The Teaching distinguishes the biblical Feast of Trumpets from later traditions associated with Rosh Hashanah and emphasizes Leviticus 23’s wording that the appointed times are the feasts of Yehovah. Leviticus 23 and Numbers 29 identify the day as the first day of the seventh month, a Sabbath rest, a holy convocation, and a day or memorial of teruah. The Teaching explains that teruah can describe a trumpet blast, alarm, loud shout, joyful cry, or triumphant proclamation. It then follows trumpet imagery through Leviticus 25, Joshua 6, Numbers 10, Nehemiah 8, Nehemiah 4, and Exodus 19, highlighting uses connected with remembrance, salvation, gathering, movement, and response. The Teaching next compares these patterns with New Testament passages concerning Yeshua’s return and the sound of a trumpet. It explicitly notes that the Bible connects Yeshua’s return with trumpet imagery but does not explicitly state that His return will occur on the Feast of Trumpets. A later section considers the call-and-response pattern in which a trumpet sounds and the people gather, move, shout, or respond. The discussion also addresses uncertainty surrounding calendar calculations and includes comments from participants about obedience, continued study, and keeping the focus on Yehovah and Yeshua.
