This week we celebrate the Feast of Trumpets, which occurs on the 1st day of the 7th month of the biblical calendar (Leviticus 23). The number “7” and the blowing of trumpets are connected. There were 7 days in circling the walls of Jericho, and 7 angelic trumpets in the Book of Revelation.
Revelation 8:2 – I saw the seven angels who stand before God, and to them were given seven trumpets.
The 7 trumpets in heaven fulfill the meaning of the day of trumpets in the 7th month. The Torah instructs us to perform a priestly or ceremonial action; the book of Revelation describes the prophetic fulfillment of that ceremony. Blowing a trumpet is a metaphor for proclaiming prophetic revelation. (Sounding a shofar without the correct message may just be blowing a lot of hot air.)
