Judges 3:12-17

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. Then he gathered to himself the people of Ammon and Amalek, went and defeated Israel, and took possession of the City of Palms. So the children of Israel served Eglon king of Moab eighteen years. But when the children of Israel cried out to the LORD, the LORD raised up a deliverer for them: Ehud the son of Gera, the Benjamite, a left-handed man. By him the children of Israel sent tribute to Eglon king of Moab. Now Ehud made himself a dagger (it was double-edged and a cubit in length) and fastened it under his clothes on his right thigh. So he brought the tribute to Eglon king of Moab. (Now Eglon was a very fat man.)
