Jeremiah to  Lamentations

The empty city lamented.

The Empty City

FE 28This is the number of people whom Nebuchadnezzar carried away captive in the 7th year of his reign: 3,023 Jews. 29In the 18th year of the reign of Nebuchadnezzar king of Babel he carried away captive from Jerusalem 832 persons. 30In the 23rd year of Nebuchadnezzar king of Babel Nebuzaradan the general of the guard carried away captive of the Jews 745 persons. All the persons were 4,600. Jeremiah 52:28-30 (Jeremiah 52:28-30 BRB)
FE Alef 1|22 1How does the city sit solitary that was full of people. How she is become like a widow she who was so great among the peoples. She who was a princess of the cities has become a tributary. Lamentations 1:1 (Lamentations 1:1 BRB)

Jeremiah tells of the fall of Jerusalem to Babylon, a reprise of the story at the end of Second Kings and Second Chronicles. The uniqueness of Jeremiah's account are the counts of Jews deported to Babylon at three different times.

Lamentations laments the fall of Jerusalem and resulting poor quality of life, but it begins by lamenting how empty the city is. A good transition from Jeremiah's deportations.

Lamentations goes on to admit fault on the part of the people of Jerusalem and Judah. Jeremiah was the voice piece on the scene who spoke faithfully for decades in an attempt to warn the people and turn what was to come, if possible. He was not heeded, but when the people rejected Yahvah's word to them, Yahvah was cleared of any guilt in connection to letting Babylon have Jerusalem, so all of Jeremiah's service had purpose.

That said Yahvah knew he would not be heeded and Jerusalem would fall, so the event actually fits into a bigger story that was already unfolding. When Israel and the Jews were deported to the nations, they took their history, their scriptures, their anointing and the promises to Abraham with them. Jesus and Paul talk about this a lot. As a result of the deportations the world was prepared for the Great Commission, so the deportations had a missionary purpose and thus are bittersweet.
