Bible Notes Online - Judges 3 - ESV
Commentary

v1-6: These verses belong with the end of chapter 2. They complete the summary of Judges.

The continuing presence of the Canaanites in the land was a serious matter. We may liken these things to the Parable of the Weeds (or Tares), in Matt 13.24-30, 36-43. The separation of the faithful from the unbelievers is not to be expected during our lifetime. The Lord Jesus referred to the end of the age, when He will separate sheep from goats. The key for the Lord's people today is how they respond to the presence and influence of the ungodly. The presence of sin in our lives may also be seen in a similar way, as we learn to trust Him, and to be repentant and humble.

Israel had to be taught to know war (v2); there is a conflict for the Christian in the world. We need to be constantly reminded of this. Although we rightly refer to the victory of the Lord Jesus, we nevertheless face real battles. In particular, there are sins that constantly threatens to spoil us, and we must be watchful and prayerful. There are enemies of the gospel, who will oppose the proclamation of the Good News of Christ.

v6: In particular, Israel made alliances with the Canaanites; see 2.2; Josh 24.16.

v7-9: The first cycle (as in 2.11-13); the people fell into idolatry (v6-7), then suffered oppression under Cushan-Rishathaim, King of Mesopotamia (v8), then cried out for deliverance; the Lord raised up Othniel as Judge. He was a proven leader and fighter (see 1.12-13); like Caleb, his relation, Othniel had a zeal for God, and commitment to carry through the task set before him.

We note that the oppression was for 8 years, and the succeeding peace was for 40 years. A cursory reading of Judges may miss the fact that, often for quite long periods, there was peace in the land. The periods of suffering and oppression were, however, quite severe.

We understand also that the oppression may have simply been in part of Israel. The events in Judges may well overlap, in terms of time as the writer describes events occuring in different regions.

v12-15: The second cycle (as in 2.11-13); the people fell into idolatry (v12), then suffered oppression under Eglon, King of Moab (v12), who dominated them for 18 years (v14). The people cried out to God, who sent Ehud (v15).

v16-18: Ehud, although armed, risked his life in returning to Eglon.

v19: The reference to idols (or stone images), may be stone quarries at Gilgal. This was a place of Israel's commitment to God (Josh 5.9). It was not far from Jericho, which Eglon had captured, so the presence of stone images (if that is what they were) may indicate Moabite idolatry. We do not necessarily draw the conclusion that Israel had set up these idols.

v20-25: The narrative here is genuine; we know that Ehud was left-handed, and that Eglon was very fat, and also that there were idols (v26).

There is the gruesome description of the slaying of Eglon - we make no objection to this. Life is sometimes gruesome and gory. Fact!

There is also the slight humour that Eglon's servants stand at the door wating, thinking he is at the toilet. We make no objection to this. Real life can be comical. Fact! 

v26-30: Ehud, having killed Eglon, gathered the people of Ephraim to fight Moab. They won a mighty victory. The reference to Ephraim suggests that the oppression under Moab was only regional; see note at v7-9 above.

v31: Shamgar, like other Judges, is given little space. Even so, he won a victory over the Philistines, and delivered Israel.
