Commentators are struck by the word "Therefore." After describing Israel's incurable sin, one might expect continued punishment. Instead, God declares He will turn on their enemies. The logic is divine, not human: "Because you are utterly helpless and your situation is incurable by human means, therefore I will intervene to save you." As Charles Spurgeon notes, this is a powerful display of God's sovereign grace, which shines brightest when all human hope is gone.
