Synopsis of the Books of the Bible, by John Nelson Darby, [1857-62], at sacred-texts.com
The following commentary covers Chapters 9, 10, 11, and 12.
After Gideon's death we see the results of this distance from God in the internal struggles which took place between the children of Israel. They are ungrateful to the house of Gideon, and war breaks out amongst them through the leader whom they set up, and who, instead of fighting with the enemies of God, only seeks dominion over the people who are now at peace (Judges 9).
The overthrow of the men of Shechem and of Abimelech is followed by temporary peace, after which the people fall again into their idolatrous iniquity, and Jehovah sells them into the hands of the nations whose gods they serve. Sorely distressed by their enemies, the children of Israel cry unto Jehovah, who reproaches them for their past conduct, and sends them back to the gods they had been worshipping. Then the people put away the strange gods from among them. Jehovah is moved with compassion (Judges 10).
Israel, without a leader, have recourse to the captain of a troop of "vain men," and promise to obey him if he will put himself at their head. Jephthah consents. But although this was a deliverance, yet we see in it all how deeply Israel had fallen. Jephthah himself suffers cruelly from his rash vow; and, moreover, when the pride of the Ephraimites led them to complain that they had not been treated with due respect, the calmness and wisdom of one who knew Jehovah as Gideon did, were not found in Jephthah. What a difference between these days and those of Joshua! God multiplies His deliverances; but this has no effect on the unbelief of the people, and their condition continues to grow worse and worse (Judges 11, 12).
After Jephthah, Israel again enjoys an interval of peace under the guidance of several judges whom God raises up. But they soon return to their former course of sin, and Jehovah delivers them into the hand of the Philistines. Samson's history gives us the commencement of Israel's relationship with these bitter enemies, which only ceased when David had subdued them. The Philistines at this period were at the height of their power. But the important thing here is the history of Samson (Judges 13-16).
