Judges 3:12-14

And the children of Israel did evil again in the sight of the LORD: and the LORD strengthened Eglon the king of Moab against Israel, because they had done evil in the sight of the LORD. And he gathered unto him the children of Ammon and Amalek, and went and smote Israel, and possessed the city of palm trees. So the children of Israel served Eglon the king of Moab eighteen years.
