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.
