Albert Barnes Commentary Jeremiah 30:5

"For thus saith Jehovah: We have heard a voice of trembling, of fear, and not of peace." — Jeremiah 30:5 (ASV)

Better, as in the margin. The prophet places his hearers in the center of Babylon and describes it as convulsed with terror as the armies of Cyrus draw near. The 'voice of trembling' is the war-cry of the advancing army: while 'fear and no peace' implies that even among the exiles, there is only alarm at the prospect of the city, where they had so long lived, being destroyed.
