Thematic Bible: Moabites, amalekites, and ammonites

And then the children of Israel went to again, and committed wickedness in the sight of the LORD. And then the LORD hardened Eglon the king of the Moabites, against the children of Israel, because they had committed wickedness before the LORD. And this Eglon gathered unto him the children of Ammon, and the Amalekites, and went and smote the children of Israel, and conquered the city of palm trees.
