2 Chronicles 20:21-22, 24

After consulting the people, Jehoshaphat appointed men to sing to the LORD and to praise him for the splendor of his holiness as they went out at the head of the army, saying: “Give thanks to the LORD, for his love endures forever.” As 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.

When 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.
