John Gill Commentary Lamentations 5:8

"Servants rule over us: There is none to deliver us out of their hand." — Lamentations 5:8 (ASV)

Servants have ruled over us
The Targum is, ''the sons of Ham, who were given to be servants to the sons of Shem, they have ruled over us;'' referring to the prophecy of Noah, (Genesis 9:26Genesis 9:27) ; or such as had been tributary to the Jews, as the Edomites; so Aben Ezra; the Babylon, an, are meant; and not the nobles and principal inhabitants only, but even their servants, had power and authority over the Jews and they were at their beck and command; which made their servitude the more disagreeable and intolerable.

[there is] none that does deliver [us] out of their hand ;
out of the hand of these servants.
