A shofar is an instrument made
out of a rams horn. Shofar blasts were sounded preceding a war to rally
the troops for action and to call the people together for prayer and
repentance. The shofar is therefore like an air raid siren that alerts
us to danger, and summons us to action. The shofar was blown on the first day of the seven
month (Tishri) to commence the Feast of Trumpets.
