Judges 3:12

And the Spirit of the LORD came upon him, and he judged Israel, and went out to war: and the LORD delivered Chushanrishathaim king of Mesopotamia into his hand; and his hand prevailed against Chushanrishathaim.

And the land had rest forty years. And Othniel the son of Kenaz died.

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.
