Since the Jews read Lamentations on the annual fast that celebrated Jerusalem's destruction as far back as tradition reaches (cf. Zech. 7:3, 5; 8:19), it may be that the writer wrote this book to be read then. Its purpose then would have been to memorialize God's faithfulness in bringing covenant punishment on His people for their unfaithfulness to the Mosaic Covenant. The book would then have taught later generations the importance of covenant faithfulness and God's faithfulness.
"The author of the Book of Lamentations was attempting to show the fulfillment of the curses presented in Deuteronomy 28."7
"It [Lamentations] is a mute reminder that sin, in spite of all its allurement and excitement, carries with it heavy weights of sorrow, grief, misery, barrenness, and pain. It is the other side of the eat, drink, and be merry' coin."8
"This is one of the most tragic books in the Bible."9
