Jeremiah

Blow ye the trumpet in Zion, and sound an alarm in my holy mountain: let all the inhabitants of the land tremble: for the day of the Lord cometh, for it is nigh at hand;

And when they shall blow with them, all the assembly shall assemble themselves to thee at the door of the tabernacle of the congregation.

Shall a trumpet be blown in the city, and the people not be afraid? shall there be evil in a city, and the Lord hath not done it?

Why do we sit still? assemble yourselves, and let us enter into the defenced cities, and let us be silent there: for the Lord our God hath put us to silence, and given us water of gall to drink, because we have sinned against the Lord.

And if ye go to war in your land against the enemy that oppresseth you, then ye shall blow an alarm with the trumpets; and ye shall be remembered before the Lord your God, and ye shall be saved from your enemies.
