God announces to all the nations of the world that he's doomed them (said the nations, "rats").
Corpses will pile up everywhere; mountains will overflow with blood.
The host of heaven and the skies themselves will disappear or be rolled up.
God's sword will be gorged with the blood and fat of all the people it killed and all the animal's sacrificed to it, in places like Bozrah and Edom.
God will turn the rivers of Edom into burning pitch. It'll be a wasteland with only birds and hedgehogs owning it.
He'll spread chaos and confusion there so that the people re-name it with the snappy title "No Kingdom There."
After it's destroyed, wild animals will move in (like ostriches and jackals) and dark forces like goat-demons and Lilith (in later Jewish legend, Adam's first wife, who became a baby-killing demon). They'll all get to chill and relax there, inhabiting it forever.
