He shall judge among the heathen, he shall fill the places with the dead bodies; he shall wound the heads over many countries. He shall judge among the heathen - David shall greatly extend his dominion, and rule over the Idumeans, Moabites, Philistines, etc.
He shall fill - with the dead bodies - He shall fill pits - make heaps of slain; there shall be an immense slaughter among his enemies.
He shall wound the heads - He shall so bring down the power of all the neighboring kings, as to cause them to acknowledge him as their lord, and pay him tribute.
