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 1:1-2
"How doth the city sit solitary, that was full of people!
how is she become as a widow!
she that was great among the nations,
and princess among the provinces,
how is she become tributary!
She weepeth sore in the night,
and her tears are on her cheeks:
among all her lovers she hath none to comfort her:
all her friends have dealt treacherously with her,
they are become her enemies"
