The Book of Judges plays out in a repeating fashion where, over the course of a few chapters, the Israelites will lose their way and stop worshipping Yahweh. Yahweh will get angry at them and sell them into slavery. They will be slaves for a period of time before someone steps up to lead the Israelites back to God, always in some insanely bloody fashion. This finally ends in a weird, disgusting little coda that I'll get to later.
Following Joshua's death, Judah is appointed to lead the Israelites into battle against the Canaanites. He brings his brother Simeon with him, and an army, and they kill 10,000 men in Bezek. The Canaanites and Perizzites are dead, and their king Adonibezek is captured. They (the army? Judah himself? the Bible is unclear) cut off his thumbs and big toes and kill him. They then go kill a bunch of other tribesmen in a couple other towns before a man named Caleb gives his daughter to a man named Othniel for killing a local king. They destroy the town of Zephath. This all happens in the span of a single chapter.
Eventually, they settle in a place called Accho, and the Israelites begin to mingle with the people there. This pisses God off because of his rule that "ye shall make no league with the inhabitants of this land; ye shall throw down their altars" (Judges 2:2). But "the children of Israel did evil in the sight of the LORD, and served Baalim" (2:11). Tack that on to the list of gods that exist in Christianity. Same with Baal and Ashtaroth, whom the Israelites now begin to serve in defiance of Yahweh. He "raised up judges, which delivered them out of the hand of those that spoiled them" but "they would not hearken unto their judges" (2:16-17).
So God abandons them and sells them into slavery under the king of Mesopotamia. If God uses slavery as a punishment for his own people, then he knows it's undesirable. If he knows it's undesirable, why does he accept the enslavement of other people for the Israelites? Rules for thee, but not for me.
Anyway, God "raised up" the aforementioned Othniel as a deliverer. Othniel kills a bunch of people including the king of Mesopotamia, and the Israelites have forty years of peace before Othniel dies.
But then they "did evil again" and God sells his chosen people into slavery under Eglon, the king of Moab, for 18 years. Then God "raised them up a deliverer" named Ehud. Ehud pulls off a gambit where he makes a knife and straps it to his leg under his clothing. He goes to Eglon, who "was a very fat man" and tells him he has a gift. When he steps close, Ehud stabs Eglon to death.
The KJV says, "the haft also went in after the blade; and the fat closed upon the blade, so that he could not draw the dagger out of his belly; and the dirt came out." (3:22) I didn't know what "the dirt came out" meant, so I went to the NIV to see the more modern translation. Turns out the NIV completely omits this line. I found out it's a comment about Eglon's feces falling out through the gash. So the NIV cuts out portions of the text that it finds disagreeable, proving the malleability and fallibility of the Bible.
Ehud escapes and then calls the Israelites together with a trumpet, they kill 10,000 Moabites, and the Israelites are free again. Another 80 years pass in peace before the cycle begins again.
This time when the Israelites do "evil in the sight of the LORD", God sells them out to Jabin, king of Canaan. Now it's Deborah who teams up with Barak to kill everyone. She hides some kings and promises to lie to people who look for them, but then sells them out anyway and they die. Everyone says a prayer of thanks to God for killing everyone. Thou shalt not kill, but thanks for doing it! 40 years of rest and then...
Next round! They do some evil and God gives them to the Midianites where they remain slaves for 7 years. Gideon is chosen to fix it. Gideon makes an offering of unleavened cake and a young goat and builds an altar there. He overthrows an altar to Baal and turns it into an altar for Yahweh. That pisses off the locals, which prompts Gideon to plead for help to Yahweh.
Despite being, you know, all powerful, and having spoken directly to his people before, Gideon instead asks for a form of communication less direct and more prone to personal interpretation. He says, "Behold, I will put a fleece of wool in the floor; and if the dew be on the fleece only, and it be dry upon all the earth beside, then shall I know that thou wilt save Israel by mine hand." (6:36) Why can't God just send another angel or something. Just be like, "Yeah, I got you." Why this weird thing where Gideon will wait for a towel to get wet?
Gideon seems to recognize how stupid this idea is when he gets up the next morning and finds a wet towel and no dew on the ground and then thinks, "let it now be dry only upon the fleece, and upon all the ground let there be dew." So that happens as well.
Well, all this dicking around winds up getting Gideon and his people surrounded by an army of Midianites. But suddenly, God doesn't want to help. God says in 7:2, "The people that are with thee are too many for me to give the Midianites into their hands, lest Israel vaunt themselves against me, saying, Mine own hand hath saved me." So God thinks the Israelites can take the Midianites on their own. Because they're capable, he thinks that even if he helps, the Israelites won't *think* he helped. It's not enough for him to free his chosen people from slavery. They have to know it's him who's doing it, or it isn't worth it. God sucks. Isn't it more moral to free people from slavery and not expect recognition and acclaim for it?
God has a solution to this: everyone should go up mount Gilead and anyone who's afraid should come back early. 10,000 people come back, and that's still too many for God, so he has Gideon bring those people down to the river. God declares, "Every one that lappeth of the water with his tongue, as a dog lappeth, him shalt thou set by himself; likewise every one that boweth down upon his knees to drink." Three hundred people drink like dogs, and God likes that. "By the three hundred men that lapped will I save you, and deliver the Midianites into thine hand." This is every bit as intentionally degrading and inhumane as any college fraternity hazing ritual.
Before the killing starts, there's this stupid dream interpretation. The dream comes to Gideon: "A cake of barley bread tumbled into the host of Midian, and came unto a tent, and smote it that it fell, and overturned it, that the tent lay along." And the interpretation according to an unnamed "fellow": "This is nothing else save the sword of Gideon the son of Joash, a man of Israel: for into his hand hath God delivered Midian, and all the host." (7:13-14) Gideon is dream bread.
Anyway, they surround the Midianite camps and kill them all. Those who run get chased down. They kill the two princes of Midian and decapitate them, then bring their severed heads back to Gideon. Gideon and his people then go on a tour of killing and destruction, until the Israelites feel safe again and ask Gideon to be their ruler. He refuses, saying that God is their ruler. He does, however, accept the earrings of every man they've killed, and manages to amass 1700 shekels of gold's worth of earrings.
Gideon ends up having a good time afterward, apparently, because he has 70 sons (and no idea how many daughters that aren't mentioned) from his "many wives".
But after he dies, the Israelites, who never learn a fucking thing, go a-whoring after other gods again. This time it's Baalim. A descendant of Gideon named Abimelech exacts a coup. He goes and kills his brothers (70 of them at once). There's some weird stuff here that I'm sure is supposed to be metaphorical where some trees talk and elect an olive tree to be their master, but the olive tree turns down the offer. So the trees try to elect a fig tree, but it won't do it either. Then the trees ask it of "the vine" which also turns it down. Finally, the trees ask "the bramble" who accepts. If this is a metaphor, I'm not sure what the message is. Maybe it's about allowing someone dangerous to be your ruler? If so, the message is lost on any worshippers of Yahweh.
Anyway, Abimelech rules over Shechem for a few years before God finally undermines him. Shechem rises up against Abimelech. Chapter 9 goes through all the details of it, but the short version is that Abimelech responds by destroying a bunch of cities and killing loads of people before he's finally caught off guard by a "certain woman" (who of course doesn't have a name because this is the Bible and women don't matter even when they do). Some men come along and stab him a few times to make sure that he's dead. And "Thus God rendered the wickedness of Abimelech."
Chapter 10 brings a new Israeli ruler, and then another, and then another. Eventually, you wind up with the "children of Israel" serving Baalim again, "and Ashtaroth, and the gods of Syria, and the gods of Zidon, and the gods of Moab, and the gods of the children of Ammon, and the gods of the Philistines" (10:6), so God sells them to the Ammonites for 18 more years. They talk to God and apologize and put away their "strange gods" and prepare again for war. There's an attempt at diplomacy, which fails, and things wind up with the Israelites needing to pass through Ammon to get back home, but Sihon, the king of the Ammonites, won't let them. And why should he? These people have a centuries-long history of raping cities. Why the hell would he let them just do that to him next?
Of course, God ends up killing the Ammonites and Sihon, and the Israelites take over their land, proving Sihon right to not let them in in the first place. They destroy 20 cities and their vineyards under the leadership of one Jephthah. There is a "very great slaughter," and "the children of Ammon were subdued before the children of Israel" (11:33). He leads them to kill Ephraim and his people over a land dispute that they've decided to just let the gods hash it out on. Afterward, they control ingress into their land, determining who is Israeli and who is an Ephremite by asking all people to say, "Shibboleth." Turns out, non-Israelites can't say that word. They end up killing 42,o00 people for not saying shibboleth right. Thou shalt not kill.
Anyway, there's this whole chain of leaders of Israel after that: Ibzan of Bethlehem, Elon of Zebulon, Abdon of Pirathon... And after Abdon dies, the Israelites go out for other gods again...
This time there's this guy named Manoah, and even though it's his wife who has significance in this story, she's not given a name. She is barren, but God tells her she'll give birth to someone who will save Israel again. Just don't cut his hair (which is actually a throwback to an Exodus-era law about bringing a razor to your hair). She follows some rules - God always has rules, but for once they're sensible ones like don't drink alcohol when you're pregnant - and eventually gives birth to Samson.
Samson grows up and decides to take a woman for his wife, but she's a Philistine and nobody supports the marriage. On the way to meet her, Samson and family are attacked by a lion, but Samson handily kills the lion. A few days later, Samson passes the lion and sees that "there was a swarm of bees and honey in the carcase of the lion." (14:8) So he eats some.
Samson holds a kind of engagement feast and invites 30 friends to whom he proposes a riddling contest. If they can answer his riddle, he'll buy them some clothing and sheets. His riddle: "Out of the eater came forth the meat, and out of the strong came forth sweetness." Now, if these friends didn't know about the event with the lion, I have no clue how the hell they're supposed to solve this riddle. It's very on the nose and topical.
Unsurprisingly, they can't answer it, and they ask Samson's wife after a week what the answer is. Actually, they threaten her with burning her father's house down. So she breaks down after a week and Samson still doesn't want to tell her. He does eventually relent, and she relays the message. They answer his riddle, but Samson knows the gig is up because there's absolutely no way they could have figured this out on their own. He accuses them of "plow[ing] with my heifer" which is a nice way to refer to his wife. So he goes and kills all of his friends for getting the answer.
Later, he wants to go have sex with his wife, but her father won't let him in. "I verily thought that thou hadst utterly hated her;" he says, "therefore I gave her to thy companion: is not her younger sister fairer than she? take her." (15:2) Gotta love that "traditional Biblical marriage" the conservatives are always going on about.
But nobody tells Samson no. He takes three hundred foxes and, two at a time, ties their tails together. He ties a firebrand between the tails and sets them loose in the Philistines' cornfields, destroying their crops entirely. So the Philistines burn Samson's wife and her father alive. So Samson decides to kill their killers.
Now the Philistines want to find a way to tie up Samson so they can torture him or whatever. They try a few things to bind him, but they all fail, and Samson ends up killing a bunch of would-be captors. Once he even kills a thousand men with the jawbone of an ass, which later pours out water that Samson revives himself with.
So Samson falls in with a harlot named Delilah, and the Philistines start trying to bribe this information from her - how can we tie Samson down? He lies to her when she asks. He tells her a few things, each of which is tried by the Philistines with failure. Tie him down with bowstrings. Tie him with brand new ropes that have never been used. Weave his hair into a loom. Finally, when she pulls the old "Don't you love me?" schtick, he tells her to shave his head. So she does, when he's asleep, and he wakes up weak.
They drag him down and tie him to pillars, not realizing that his hair is growing with magical speed, and he breaks loose, tearing down the whole building and killing everyone in it.
And now for the weird coda. This guy named Micah takes in a Danite who has been dispatched to spy the land, and makes a household priest of him. A group of men follows up on that and are mad about the guy being a priest now, so they steal Micah's religious idols.
The story shifts to an unnamed Levite whose concubine leaves him to live with her father. He follows after her and ends up staying at the father's house for a few days. Some men of the city demand that the Levite be turned out so they can rape him. The man offers his daughter up instead. She dies of gang rape, so the Levite chops her body into 12 pieces and sends them off to the tribes of Israel, who bombard the city and kill everyone. I'm out of space to finish this, so suffice it to say they kill hundreds of virgins and sell many others into rape, and THAT'S THE BOOK OF JUDGES! Not the most moral of books.
