21 And he consulted with the people, and he appointed singers to the LORD and praisers to praise the beauty of holiness as they went out before the army, and to say, Praise the LORD, for His mercy [endures] forever.
22 And when they began to sing and to praise, the LORD set ambushes against the sons of Ammon, Moab, and mount Seir, who had come against Judah. And they were beaten.
