Our pursuers are on our necks: We are weary, and have no rest.
These verses describe the condition of the poorest people of the land who had been left behind by the Chaldean conquerors.  The land owners were not these poor Israelites but the Assyrians and Egyptians who also laid heavy tribute upon them.  In addition to that the Babylonian `servants' (governors) over them also exacted heavy taxes to be forwarded to Babylon. The people were not allowed any rest, for they were essentially slaves.
