2 Chronicles 20:22

19 And the Levites of the sons of Caath, and of the sons of Core praised the Lord the God of Israel with a loud voice, on high.

20 And they rose early in the morning, and went out through the desert of Thecua: and as they were marching, Josaphat standing in the midst of them, said: Hear me, ye men of Juda, and all the inhabitants of Jerusalem: believe in the Lord your God, and you shall be secure: believe his prophets, and all things shall succeed well.

21 And he gave counsel to the people, and appointed the singing men of the Lord, to praise him by their companies, and to go before the army, and with one voice to say: Give glory to the Lord, for his mercy endureth for ever.

22 And when they began to sing praises, the Lord turned their ambushments upon themselves, that is to say, of the children of Ammon, and of Moab, and of mount Seir, who were come out to fight against Juda, and they were slain.

23 For the children of Ammon, and of Moab, rose up against the inhabitants of mount Seir, to kill and destroy them: and when they had made an end of them, they turned also against one another, and destroyed one another.

24 And when Juda came to the watch tower, that looketh toward the desert, they saw afar off all the country, for a great space, full of dead bodies, and that no one was left that could escape death.

25 Then Josaphat came, and all the people with him to take away the spoils of the dead, and they found among the dead bodies, stuff of various kinds, and garments, and most precious vessels: and they took them for themselves, insomuch that they could not carry all, nor in three days take away the spoils, the booty was so great.
