Albert Barnes Commentary Jeremiah 12:14

"Thus saith Jehovah against all mine evil neighbors, that touch the inheritance which I have caused my people Israel to inherit: behold, I will pluck them up from off their land, and will pluck up the house of Judah from among them." — Jeremiah 12:14 (ASV)

The prophet addresses the spoilers.

Evil neighbors: The Syrians, Edomites, Moabites, Ammonites, and Philistines, who at all times took advantage of Judah’s weakness. The special mercy to Judah was the prelude to mercy to the whole Gentile world.
