Albert Barnes Commentary Jeremiah 12:7-9

"I have forsaken my house, I have cast off my heritage; I have given the dearly beloved of my soul into the hand of her enemies. My heritage is become unto me as a lion in the forest: she hath uttered her voice against me; therefore I have hated her. Is my heritage unto me as a speckled bird of prey? are the birds of prey against her round about? go ye, assemble all the beasts of the field, bring them to devour." — Jeremiah 12:7-9 (ASV)

Yahweh shows that the downfall of the nation was not caused by any lack of love on His part, but by the nation’s conduct.

Left (Jeremiah 12:8)—more correctly, cast away.

Judah has not merely refused obedience, but become intractable and fierce, like an untamed lion. It has roared against God with open blasphemy. As His favor is life, so His hatred is death; that is, Jerusalem’s punishment will be as if inflicted by one who hated her.

Regarding Jeremiah 12:9, a more accurate rendering of the verse is: Is My heritage unto Me as a speckled bird? Are the birds upon her round about? Come, assemble all the wild beasts: bring them to devour her. By “a speckled” or parti-colored “bird” is probably meant some kind of vulture.
