2 Chronicles 20:22-25

22The moment they began their shouts and praises, the LORD set ambushes against the men of Ammon, Moab, and Mount Seir who had come against Judah, and they were defeated. 23The Ammonites and Moabites rose up against the inhabitants of Mount Seir, devoting them to destruction.1 And when they had finished off the inhabitants of Seir, they helped to destroy one another.

24When the men of Judah came to a place overlooking the wilderness, they looked for the vast army, but there were only corpses lying on the ground; no one had escaped. 25Then Jehoshaphat and his people went to carry off the plunder, and they found on the bodies an abundance of goods and valuables2—more than they could carry away. They were gathering the plunder for three days because there was so much.
