Thematic Bible: Army choir and songs

Then he consulted with the people and appointed some to sing for the Lord and some to praise the splendor of [His] holiness. When they went out in front of the armed forces, they kept singing: Give thanks to the Lord, for His faithful love endures forever. The moment they began [their] shouts and praises, the Lord set an ambush against the Ammonites, Moabites, and [the inhabitants of] Mount Seir who came [to fight] against Judah, and they were defeated.
