21 After discussion with the people, he appointed singers to praise the Lord for his glorious, holy goodness. They led the way at the front of the army, singing, "Praise the Lord, for his trustworthy love lasts forever!"

22 As soon as they started singing and praising, the Lord ambushed the men of Ammon, Moab, and Mount Seir who were coming to attack Judah, and they were defeated.
