Shofar (by Alphonse Lévy)
The shofar is mentioned frequently in the Hebrew Bible, the Talmud and rabbinic literature. The blast of a shofar emanating from the thick cloud on Mount Sinai made the Israelites tremble in awe (Exodus 19, 20).
The shofar was used in biblical times to announce the New Moon, holidays (Num. x. 10; Ps. lxxxi. 4), and the Jubilee year (Lev. 25. 9). The first day of the seventh month (Tishri) is termed "a memorial of blowing" (Lev. 23. 24), or "a day of blowing" (Num. xxix. 1), the shofar. It was also employed in processions (II Sam. 6. 15; I Chron. 15. 28), as a musical accompaniment (Ps. 98. 6; comp. ib. xlvii. 5) and to signify the start of a war (Josh. 6. 4; Judges 3. 27; 7. 16, 20; I Sam. 8. 3).
The Torah describes the first day of the seventh month (1st of Tishri = Rosh ha-Shanah) as a zikron teruah (memorial of blowing; Lev. xxiii) and as a yom teru'ah (day of blowing; Num. 29). This was interpreted by the Jewish sages as referring to the sounding the shofar.
In the Temple in Jerusalem, the shofar was sometimes used together with the trumpet. On New-Year's Day the principal ceremony was conducted with the shofar, which instrument was placed in the center with a trumpet on either side; it was the horn of a wild goat and straight in shape, being ornamented with gold at the mouthpiece. On fast-days the principal ceremony was conducted with the trumpets in the center and with a shofar on either side. On those occasions the shofarot were rams' horns curved in shape and ornamented with silver at the mouthpieces. On Yom Kippur of the jubilee year the ceremony was performed with the shofar as on New-Year's Day.
The shofar was blown in the times of Joshua to help him capture Jericho. As they surrounded the walls the shofar was blown and the Jews were able to capture the city. The shofar was commonly taken out to war so the troops would know when a battle would begin. The person who would blow the shofar would call out to the troops from atop a hill. All of the troops were able to hear the call of the shofar from their position because of its distinct noise.
