2 Chronicles 20:23

For the children of Ammon and Moab stood up against the inhabitants of Mount Seir,.... Supposing that they had acted a treacherous part by them, and took on the side of their enemies:

utterly to slay and destroy them; as they did:

and when they had made an end of the inhabitants of Seir; so that there were none left of them:

everyone helped to destroy one another; in their confusion mistook one another, either for Edomites or Jews, like the Midianites in the times of Gideon.
