4 19 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. 4 20 Disaster follows hard on disaster, the whole land is laid waste. Suddenly my tents are destroyed, my curtains in a moment. 4 21 How long must I see the standard, and hear the sound of the trumpet? 4 22 "For my people are foolish, they know me not; they are stupid children, they have no understanding. They are skilled in doing evil, but how to do good they know not."
