2 Chronicles 20:22-26

As they began to sing and praise God, the LORD set ambushes for the people of Ammon, Moab, and Edom who had come to attack Judah. And they were defeated. The Ammonites and Moabites attacked the Edomites, destroying them completely. After they had killed the Edomites, they killed each other. When the men from Judah came to a place where they could see the desert, they looked at the enemy’s large army. But they only saw dead bodies lying on the ground; no one had escaped. When Jehoshaphat and his army came to take their valuables, they found many supplies, much clothing, and other valuable things. There was more than they could carry away; there was so much it took three days to gather it all. On the fourth day Jehoshaphat and his army met in the Valley of Beracah and praised the LORD. That is why that place has been called the Valley of Beracah to this day.
