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 4:12-14
"The kings of the earth, and all the inhabitants of the world,
would not have believed that the adversary and the enemy
should have entered into the gates of Jerusalem.
For the sins of her prophets,
and the iniquities of her priests,
that have shed the blood of the just in the midst of her,
they have wandered as blind men in the streets,
they have polluted themselves with blood,
so that men could not touch their garments"
