Charles Ellicott Commentary Lamentations 1:13

"From on high hath he sent fire into my bones, and it prevaileth against them; He hath spread a net for my feet, he hath turned me back: He hath made me desolate and faint all the day." — Lamentations 1:13 (ASV)

From above ... —The words are probably figurative. The judgments that had fallen on Jerusalem were as a fire from heaven, piercing even to the joints and marrow, the innermost recesses of life.

He has turned me back ... —The phrase points not to the defeat and flight of battle, but, completing the figure of the net, paints the failure of every effort to escape. The word for “desolate” implies, as in the case of Tamar (2 Samuel 13:20), an utter, hopeless misery.
