2 Chronicles 20:22-26

22As they started to sing praises, the Lord set ambushes against the Ammonites, Moabites, and the people of Mount Seir who had come into Judah. They were defeated.

23Then the Ammonites and Moabites attacked the people from Mount Seir and annihilated them. After they had finished off the people of Seir, they helped destroy one another.

24The people of Judah went to the watchtower in the desert and looked for the crowd. Corpses were lying on the ground. No one had escaped.

25When Jehoshaphat and his troops came to take the loot, they found among them a lot of goods, clothes, and valuables. They found more than they could carry. They spent three days collecting the loot.

26On the fourth day they gathered in the valley of Beracah. Because they thanked the Lord there, that place is still called the valley of Beracah [Thanks] today.
