| A shofar is a ram's horn that is used as a musical instrument for religious purposes. It is used on Judaism's high holy days of Rosh Hashanah and Yom Kippur. |
The shofar is mentioned frequently in the Hebrew Bible, from Exodus to Zechariah, and throughout the Talmud and later rabbinic literature. It was the voice of a shofar, "exceeding loud," issuing from the thick cloud on Mount Sinai that made all the Israelites tremble in awe (Exodus xix, xx).
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.
