2 Chronicles 20:20-24

Thomson(i) 20 And they arose early in the morning, and went out to the wilderness of Thekoe. And as they were marching out, Josaphat stood and cried with a loud voice, and said, Hear me, Juda, and ye inhabitants of Jerusalem. Trust in the Lord our God, and you shall be confirmed in your confidence. Confide in his prophet, and you shall prosper. 21 Then he consulted with the people, and appointed the musicians, and them who sing praises, to give thanks and to sing the holy songs of praise. So marching at the head of the army, they sung the hymn, praise the Lord, for his mercy endureth forever. 22 And when they began the song of thanksgiving and praise, the Lord set a fighting the Ammonites against Moab and Mount Seir, who were going out against Juda; And when they were repelled, 23 the Ammonites and Moab rose upon the inhabitants of Seir to exterminate and destroy them. And when they had made an end of the inhabitants of Seir, they rose up one against the other till they were utterly destroyed. 24 So when Juda came to the watch tower of the wilderness, and looked and took a view of the multitude, behold they all lay dead on the ground. Not one had escaped.
