Albert Barnes Commentary Lamentations 2:11

"Mine eyes do fail with tears, my heart is troubled; My liver is poured upon the earth, because of the destruction of the daughter of my people, Because the young children and the sucklings swoon in the streets of the city." — Lamentations 2:11 (ASV)

Troubled - See the margin reference note.

Liver - As the heart was regarded by the Jews as the seat of the intellect, so the liver (or bowels) was supposed to be the seat of the emotions. The pouring out of the liver upon the ground meant that feelings had entirely given way under the acuteness of sorrow, and he could no longer restrain them.
