2 Chronicles 20:20-25

20Early in the morning they left for the Desert of Tekoa. As they set out, Jehoshaphat stood and said, “Listen to me, Judah and people of Jerusalem! Have faith in the LORD your God and you will be upheld; have faith in his prophets and you will be successful.”

21After consulting the people, Jehoshaphat appointed men to sing to the LORD and to praise him for the splendor of his Or him with the splendor of holiness as they went out at the head of the army, saying: “Give thanks to the LORD, for his love endures forever.” 22As they began to sing and praise, the LORD set ambushes against the men of Ammon and Moab and Mount Seir who were invading Judah, and they were defeated.

23The Ammonites and Moabites rose up against the men from Mount Seir to destroy and annihilate them. After they finished slaughtering the men from Seir, they helped to destroy one another. 24When the men of Judah came to the place that overlooks the desert and looked toward the vast army, they saw only dead bodies lying on the ground; no one had escaped. 25So Jehoshaphat and his men went to carry off their plunder, and they found among them a great amount of equipment and clothing Some Hebrew manuscripts and Vulgate; most Hebrew manuscripts corpses and also articles of value—more than they could take away. There was so much plunder that it took three days to collect it.
