21 And after discussion with the people, he put in their places those who were to make melody to the Lord, praising him in holy robes, while they went at the head of the army, and saying, May the Lord be praised, for his mercy is unchanging for ever.
22 And at the first notes of song and praise the Lord sent a surprise attack against the children of Ammon and Moab and the people of Mount Seir, who had come against Judah; and they were overcome.
