2 Chronicles 20:21-23

21st Century King James Version

²¹ And when he had consulted with the people, he appointed singers unto the Lord who should praise the beauty of holiness as they went out before the army, and to say, “Praise the Lord, for His mercy endureth for ever.”

²² And when they began to sing and to praise, the Lord set ambushes against the children of Ammon, Moab, and Mount Seir, who had come against Judah; and they were smitten.

²³ For the children of Ammon and Moab stood up against the inhabitants of Mount Seir utterly to slay and destroy them; and when they had made an end of the inhabitants of Seir, every one helped to destroy another.
