Albert Barnes Commentary Jeremiah 49:30

"Flee ye, wander far off, dwell in the depths, O ye inhabitants of Hazor, saith Jehovah; for Nebuchadrezzar king of Babylon hath taken counsel against you, and hath conceived a purpose against you." — Jeremiah 49:30 (ASV)

A purpose against you - Others read “against them” (the wealthy nation, Jeremiah 49:31).
