Cushan-rishathaim was in Mesopotamia; Eglon lived in a neighbouring state, just across the Jordan River. The Lord had sold
Israel into Cushan’s hand and they had to serve him for eight years. Now, however, this enemy’s hold on Israel was stronger and lasted longer: the Lord strengthened Eglon…against Israel,
so that he defeated Israel and exercised power over Israel for eighteen years, ten years longer than Cushan-Rishathaim.1
12 And the people of Israel again did what was evil in the sight of the LORD, and the LORD strengthened Eglon the king of Moab against Israel, because they had done what was evil in the sight of the LORD.
