And in that day a great trumpet will sound. Those who were perishing in Assyria and those who were exiled in Egypt will come and worship the Lord on the holy mountain in Jerusalem.
Oh, my anguish, my anguish! I writhe in pain. Oh, the agony of my heart! My heart pounds within me, I cannot keep silent. For I have heard the sound of the trumpet; I have heard the battle cry.
Blow the trumpet in Zion; sound the alarm on my holy hill. Let all who live in the land tremble, for the day of the Lord is coming. It is close at hand—
When you go into battle in your own land against an enemy who is oppressing you, sound a blast on the trumpets. Then you will be remembered by the Lord your God and rescued from your enemies.
