2 Chronicles 20:21-22

[21] And when he had consulted  with the people,  he appointed  singers  unto the LORD,  and that should praise  the beauty  of holiness,  as they went out  before  the army,  and to say,  Praise  the LORD;  for his mercy  endureth for ever.  [22] And when  they began  to sing  and to praise,  the LORD  set  ambushments  against the children  of Ammon,  Moab,  and mount  Seir,  which were come  against Judah;  and they were smitten.
