2 Chronicles 20:22-25

At the very moment they began to sing and give praise, the LORD caused the armies of Ammon, Moab, and Mount Seir to start fighting among themselves. The armies of Moab and Ammon turned against their allies from Mount Seir and killed every one of them. After they had destroyed the army of Seir, they began attacking each other. So when the army of Judah arrived at the lookout point in the wilderness, all they saw were dead bodies lying on the ground as far as they could see. Not a single one of the enemy had escaped. King Jehoshaphat and his men went out to gather the plunder. They found vast amounts of equipment, clothing, and other valuables—more than they could carry. There was so much plunder that it took them three days just to collect it all!
