ISAIAH 18:3

All you who live in the world And inhabit the earth, When a flag is raised in the hills, take note! When a ram’s horn is blown, give heed! ISAIAH 18:3 (The Israel Bible™)

The significance of the shofar dates to the dawn of Jewish history. In the Torah, the shofar serves various purposes, both practical and spiritual. It was sounded during military operations, such as the battle of Jericho in Joshua 6. The shofar is intimately connected to Rosh Hashanah, the Jewish New year; the Torah refers to Rosh Hashanah as the “day of the shofar blast.” The blowing of the shofar awakens our slumbering souls and urges us to repent and evokes the collective memory of the shofar blasts that accompanied the receiving of the Torah on Mount Sinai. Many believe that the shofar blasts of today foreshadow the shofar blasts we will hear in the End of Days, as described in the above verse.
