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 1:21-22
"They have heard that I sigh:
there is none to comfort me:
all mine enemies have heard of my trouble;
they are glad that thou hast done it:
thou wilt bring the day that thou hast called,
and they shall be like unto me.
Let all their wickedness come before thee;
and do unto them, as thou hast done unto me
for all my transgressions:
for my sighs are many,
and my heart is faint"
