2 Chronicles 20:21-23

Amplified Bible, Classic Edition

²¹ When he had consulted with the people, he appointed singers to sing to the Lord and praise Him in their holy [priestly] garments as they went out before the army, saying, Give thanks to the Lord, for His mercy and loving-kindness endure forever!

²² And when they began to sing and to praise, the Lord set ambushments against the men of Ammon, Moab, and Mount Seir who had come against Judah, and they were [self-] slaughtered;

²³ For [suspecting betrayal] the men of Ammon and Moab rose against those of Mount Seir, utterly destroying them. And when they had made an end of the men of Seir, they all helped to destroy one another.
