2 Chronicles 20:22-25

22And when they began to sing and to praise, the LORD set liers in wait against the children of Ammon, Moab, and mount Seir, which were come against Judah; and they were smitten.

23For the children of Ammon and Moab stood up against the inhabitants of mount Seir, utterly to slay and destroy them: and when they had made an end of the inhabitants of Seir, every one helped to destroy another.

24And when Judah came to the watch-tower of the wilderness, they looked upon the multitude; and, behold, they were dead bodies fallen to the earth, and there were none that escaped.

25And when Jehoshaphat and his people came to take the spoil of them, they found among them in abundance both riches and dead bodies, and precious jewels, which they stripped off for themselves, more than they could carry away: and they were three days in taking of the spoil, it was so much.
