Jeremiah and Lamentations were written by the prophet Jeremiah during the late 7th and early 6th centuries BC as Babylon gained power in the region and ultimately destroyed Jerusalem and exiled its people. Jeremiah prophesied judgment on Judah for their sins but also promised future restoration. Lamentations expresses grief over the fall of Jerusalem from the destruction prophesied by Jeremiah. Both books share the themes of God's judgment on sin but also his faithfulness and hope for the future.
