2 Chronicles 20:22-25

22And when they began the song of triumph and praise, Jehovah set liers-in-wait against the children of Ammon, Moab, and mount Seir, who had come against Judah, and they were smitten.

23And the children of Ammon and Moab stood up against the inhabitants of mount Seir, to exterminate and destroy [them]; and when they had made an end of the inhabitants of Seir, they helped to destroy one another.

24And Judah came on to the mountain-watch in the wilderness, and they looked toward the multitude; and behold, they were dead bodies fallen to the earth, and none had escaped.

25And Jehoshaphat and his people came to plunder the spoil of them, and they found among them in abundance, both riches with the dead bodies, and precious things, and they stripped off for themselves more than they could carry away; and they were three days in plundering the spoil, it was so much.
