The term Hebrew Horn is referring to the SHOFAR, a musical instrument made from a ram's horn that is used in Jewish religious ceremonies. The SHOFAR is blown during Rosh Hashanah and Yom Kippur, two of the holiest days in the Jewish calendar. It is also used to mark the beginning of the Sabbath and other special occasions. The sound of the SHOFAR is said to be a call to repentance and a reminder of God's presence.
