Lamentations talks about the Babylonians.
The third of the Prophetical Books, and the twenty-fifth book of the Bible, is the Book of Lamentations. It is the second book to be written by the prophet Jeremiah, and, where the first book looks forward, warning of the coming destruction of Jerusalem, Lamentations looks back in mourning at the fate of the city and its people. It contains five poems which describe the destruction of Jerusalem by the Babylonians and grieve for its loss. But the Book of Lamentations also reminds us of God's faithfulness and that He will not abandon His chosen people. God's mercies remain for those who answer His call.
Lamentations 5:19-21
"Thou, O Lord, remainest for ever;
thy throne from generation to generation.
Wherefore dost thou forget us for ever,
and forsake us so long time?
Turn thou us unto thee, O Lord, and we shall be turned;
renew our days as of old"
