Judges 3:11-12, 30

So the land had rest for forty years. Then Othniel the son of Kenaz died. And the children of Israel again did evil in the sight of the LORD. So the LORD strengthened Eglon king of Moab against Israel, because they had done evil in the sight of the LORD.

So Moab was subdued that day under the hand of Israel. And the land had rest for eighty years.
