Judges 1:30

A new generation arises that does not know the Lord or the works He has done for Israel. This generation forsakes the God of their fathers, turning to worship the Baals and Ashtaroth of the surrounding peoples. This apostasy provokes the Lord's anger, and He hands them over to their enemies, who oppress them. When the Israelites cry out to the Lord in their misery, He raises up judges—deliverers who save them from their oppressors. However, as soon as a judge dies, the people relapse into even greater corruption, returning to their idolatrous ways. This establishes the book's central, recurring cycle: sin, oppression, repentance, and deliverance, followed by a period of rest, and then a return to sin. Judges 3: Othniel, Ehud, and Shamgar The first cycle of judgment begins as the Israelites do evil in the sight of the Lord and worship idols. God's anger burns against them, and He sells them into the hands of Cushan-Rishathaim, king of Mesopotamia, whom they serve for eight years. When the people cry out to the Lord, He raises up Othniel, the younger brother of Caleb, as their deliverer. The Spirit of the Lord comes upon him, and he leads Israel to victory, defeating the Mesopotamian king. The land has peace for forty years until Othniel's death. After Othniel dies, the Israelites again do evil, and God strengthens Eglon, the king of Moab, against them. Eglon, allied with the Ammonites and Amalekites, defeats Israel and captures the city of palms, Jericho. The Israelites are subject to Moab for eighteen years. When they cry out for help, God raises up Ehud, a left-handed man from the tribe of Benjamin. While delivering Israel's tribute, Ehud uses his left-handedness to his advantage, concealing a dagger on his right thigh. In a private audience with the obese King Eglon, he claims to have a secret message from God and stabs the king in the belly. Ehud escapes, rallies the Israelite forces, and leads them to a decisive victory over the Moabites, killing about 10,000 of their soldiers. The land enjoys peace for eighty years. After Ehud, Shamgar son of Anath is mentioned, who strikes down 600 Philistines with an oxgoad, also saving Israel.
