2 Chronicles 20:20-25

And they rose early in the morning and went out into the wilderness of Tekoa. And when they went out, Jehoshaphat stood and said, “Hear me, Judah and inhabitants of Jerusalem! Believe in the LORD your God, and you will be established; believe his prophets, and you will succeed.” And when he had taken counsel with the people, he appointed those who were to sing to the LORD and praise him in holy attire, as they went before the army, and say, “Give thanks to the LORD, for his steadfast love endures forever.” And when they began to sing and praise, the LORD set an ambush against the men of Ammon, Moab, and Mount Seir, who had come against Judah, so that they were routed. For the men of Ammon and Moab rose against the inhabitants of Mount Seir, devoting them to destruction, and when they had made an end of the inhabitants of Seir, they all helped to destroy one another. LORD When Judah came to the watchtower of the wilderness, they looked toward the horde, and behold, there were dead bodies lying on the ground; none had escaped. When Jehoshaphat and his people came to take their spoil, they found among them, in great numbers, goods, clothing, and precious things, which they took for themselves until they could carry no more. They were three days in taking the spoil, it was so much.
