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.
"Rejoice and be glad, O daughter of Edom,
that dwellest in the land of Uz;
the cup also shall pass through unto thee:
thou shalt be drunken,
and shalt make thyself naked.
The punishment of thine iniquity is accomplished,
O daughter of Zion;
he will no more carry thee away into captivity:
he will visit thine iniquity,
O daughter of Edom;
he will discover thy sins"
Jeremiah says that though the Jews' punishment will one day come to an end, Edom's punishment will last forever
