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 host: 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 dwelt, being destroyed.

We have heard a voice of trembling - This may refer to the state and feelings of the people during the war which Cyrus carried on against the Babylonians. Trembling and terror would no doubt affect them, and put an end to peace and all prosperity; as they could not tell what would be the issue of the struggle, and whether their state would be better or worse should their present masters fall in the conflict. This is well described in the next verse, where men are represented as being, through pain and anguish, like women in travail. See the same comparison Isaiah 13:6-8.

For thus saith the LORD; We have heard a (b) voice of trembling, of fear, and not of peace.
(b) He shows that before this deliverance will come, the Chaldeans would be extremely afflicted by their enemies, and that they would be in such perplexity and sorrow as a woman in her travail as (Isaiah 13:8).

For thus saith the Lord,.... Yet what follows are the words of others; wherefore some supply it, "for thus saith the Lord, the nations shall say" (p); so Kimchi and Ben Melech interpret it as what the Gentiles will say in the times of the Messiah; but it might be better supplied, "ye shall say"; that is, Israel and Judah; to whom the words of the Lord are spoken in Jeremiah 30:3; or else the Lord here represents his people, saying:
we have heard a voice of trembling, ear, and not of peace; which is to be understood, of the fear and dread injected into them by the Babylonians when they besieged their city, and burned that, and their temple; nor of the fear and dread which came upon the Babylonians at the taking of their city by Cyrus, upon which followed the deliverance of the Jews. Kimchi interprets this of something yet future, the war of Gog and Magog, which he supposes wilt be when their Messiah comes; and Jarchi sans it is so understood in their Midrash Agadah. This distress, I think, refers to the slaying of the witnesses, and to that hour of temptation which shall come upon all the earth to try the inhabitants of it; and which will be followed with the destruction of antichrist; and that will make way for the call and conversion of the Jews.

We have heard . . . trembling--God introduces the Jews speaking that which they will be reduced to at last in spite of their stubbornness. Threat and promise are combined: the former briefly; namely, the misery of the Jews in the Babylonian captivity down to their "trembling" and "fear" arising from the approach of the Medo-Persian army of Cyrus against Babylon; the promise is more fully dwelt on; namely, their "trembling" will issue in a deliverance as speedy as is the transition from a woman's labor pangs to her joy at giving birth to a child (Jeremiah 30:6).
