The shofar is not only the sound of our reward, it is also considered a spiritual weapon of warfare. As we pray and sound the shofar in our homes and over our families it sends a clear signal that we are pulling down every stronghold of the enemy. 2 Corinthians 10:4
says; For the weapons of our warfare are not carnal but mighty in God for pulling down strongholds...
Gid'on's men blew their 300 shofars, and Adonai caused everyone in the camp to attack his
comrades; and the enemy fled. Judges 7:22 CJB
