'Sound of the Trumpet' 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.

How long [O Lord] must I see the banner [marking the way for flight]And hear the sound of the trumpet [urging the people to run for safety]?

“I have set watchmen (prophets) over you,Saying, ‘Listen and pay attention to the [warning] sound of the trumpet!’But they said, ‘We will not listen.’

saying, “No, but we will go to the land of Egypt, where we will not see war or hear the sound of the [warrior’s] trumpet or hunger for bread, and we will stay there,”
