And on that day a great trumpet will be blown, and those who were lost in the land of Assyria and those who were driven out to the land of Egypt will come and worship the Lord on the holy mountain at Jerusalem.
My anguish, my anguish! I writhe in pain! Oh, the walls of my heart! My heart is beating wildly; I cannot keep silent, for I hear the sound of the trumpet, the alarm of war.
Blow the trumpet in Zion; sound the alarm on my holy mountain! Let all the inhabitants of the land tremble, for the day of the Lord is coming, it is near—
When you go to war in your land against the adversary who oppresses you, you shall sound an alarm with the trumpets, so that you may be remembered before the Lord your God and be saved from your enemies.
