Albert Barnes Commentary Jeremiah 50:7

"All that found them have devoured them; and their adversaries said, We are not guilty, because they have sinned against Jehovah, the habitation of righteousness, even Jehovah, the hope of their fathers." — Jeremiah 50:7 (ASV)

Offend not – that is, “are not guilty.” Israel, having left the fold, has no owner and may therefore be maltreated with impunity.

Habitation of justice – In (Jeremiah 31:23) this is applied to Jerusalem: here, Yahweh alone is the true pasturage, in whom His people will find safety, rest, and plenty.
