Shofars are made from ram or antelope horns and are traditionally blown during the Jewish high holidays, which is the period of repentance in the Jewish calendar. Photo by Debbie Hill/UPI

The blowing of the shofar marks the beginning of 10 days of penitence, which ends with Yom Kippur. Photo by Debbie Hill/UPI

The shofar symbolizes the passage from the Torah read on Rosh Hashanah, which tells the story of how Abraham killed a ram that was stuck in a bush instead of sacrificing his son. Photo by Debbie Hill/UPI
