Jeremiah
We have in Jeremiah, the present dealing of God with rebellious Judah. Judah becomes Lo-ammi (not my people) by the captivity in Babylon.
Then, from chapter 30, we have the revelation of the infallible love of Jehovah to Israel (Judah and Ephraim). We have the certainty of their establishment under David, according to the order of God, in Jerusalem, Jehovah being their righteousness. Then, after the history of Zedekiah, and the details of what brought in the captivity, and what passed in Palestine after that, we have the judgment of all the nations and Babylon itself.
Lamentations
In Lamentations we get the sympathy and entering in of the Spirit of Christ into the sorrows of Israel, especially the remnant, and the hope of restoration.
