Lamentations

This book's author is unknown, but there's good reason to presume it was Jeremiah. It was read on the annual fast for Jerusalem's destruction from as far back as anyone could remember, in the hope that future generations of Hebrews would not repeat the wickedness of their ancestors. The 5 chapters are 5 separate laments or dirges.
