'Silent' in the Bible

My soul, my soul! I writhe in anguish and pain! Oh, the walls of my heart!My heart is pounding and throbbing within me;I cannot be silent,For you have heard, O my soul,The sound of the trumpet,The alarm of war.

Why are we sitting still [the people wonder]?Assemble yourselves, and let us enter the fortified citiesAnd let us die there,For the Lord our God has decreed our ruinAnd given us bitter and poisonous water to drink,Because we have sinned against the Lord.
