These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
In some versions, especially Sufism, Satan is a yandere to God.
Generally Lucifer is thought to be the name Satan had before he fell, but some think he is a separate person from him.
Is Leviathan Satan, a crocodile, dragon, dinosaur, submarine or something else?
Is Behemoth a hippo, elephant, dinosaur, or something else?
Are these 3 merely personification of the untamable elements of land, sea and air?
As sacrificing humans was against the law, some interpretations say that Jephthah's daughter's sacrifice actually meant service to God; she wept over her virginity because dedication to God meant she'd never get to marry and have a family, meaning she'd keep that virginity forever. And family was kind of a big deal for Jewish women back in those days.
Big Lipped Alligator Moment: Exodus 4:24-26. God attacks and tries to kill Moses prompting Moses's wife to circumcise Moses's son and throws the foreskin at Moses's feet. This act makes God let Moses go. This moment comes out of nowhere and is never mentioned again.
Broken Base: Easily the most divisive work in the history of literature.
Complete Monster: Haman from the Book of Esther. He was a treacherous advisor offended by one Jew's refusal to bow to him, using this as justification for plotting the genocide of the Jewish people. Various Judaic traditions elaborate on this, noting Haman had a picture of an idol embroidered onto his robes so that he could force Jews bowing to him to violate the taboo against kneeling to idols. The very trees from which he hoped to build his gallows recoiled from his unclean presence, and unlike some Biblical antagonists, he's not an agent of divine retribution, just a self-important bastard who can't accept being disrespected. Even Haman's wife tells to his face that he has gone over the line, and that his obsession with killing the Jews would soon become self-destructive; he ignores her and goes ahead with his plans. His name has become a watchword for anti-Semitism and he is viewed in rabbinical tradition as an archetypal evil figure.
Jesus. He could have called thousands of angels to smite His killers, but He chose to bear all the pain and suffering to save all who would believe.
Samson's final moments are spent bringing down the Philistine government, while also killing more men than he ever had in his life.
The emperor Nero ordered Peter to be crucified, thus putting himself above Peter in a power dynamic. Peter asked to be crucified upside down, thus outdoing Nero. (Doubles as Tear Jerker since Peter also did it because he believed himself unworthy of dying like Jesus)
Paul was about to be crucified, but then he told his would-be executers: 'Hey, I'm a Roman. Kill me if you want, but I've my right to tell you how I will die.' That takes quite the balls.
Protestants (and Jews) rejected the additional (as in, those not in the Masoretic text of the Tanakh) Old Testament books that came from the Greek Septuagint and call them "apocrypha" (not Canon), whereas they're considered Canon by Catholics.
Then there's the New Testament "apocrypha," some of which are just weird. The Infancy Gospel of Thomas, for instance, is possibly the first example of Super Dickery, featuring a very young Jesus that blinds, kills, and heals people left and right, then proceeds to lecture his teacher on theology. Mainstream Christians reject the Gospel of Thomas, which was widely read by early Christian communities, on the basis of its much later origin and the fact that it was most certainly not written by Thomas or anyone in his general time period. The Nicean council ruled that it wasn't authentic.
The entire New Testament is rejected by the Jews; most Christians reject the Book of Mormon, except for the Mormons. Only the Muslims accept the canonicity of the Koran.
A lot of people (and the nation of Ethiopia) believe the Queen of Sheba was one of Solomon's lovers.
Mary Magdalene and Jesus is this to Gnostics and Dan Brown
Freud Was Right: God demands Abraham circumcise himself and those of his house, then demands he sacrifice his son. God changes His mind at the end.
Internet Backdraft: Perhaps nothing in this world can easily start a Flame War more than the Bible itself. Heated debates regarding pretty much anything inside it have, are, and will occur between different religions, non-religious views, and even amongst religions themselves. The main page is locked for a reason.
Samson is presented as a flawed figure who abuses his powers, gets screwed over for it, and ends up dying because there's nowhere else to go. Yet, many readers can't look over his Rated M for Manly antics and celebrate him as a Memetic Badass who dies in a blaze of glory. He's almost like the Kamina of the ancient world.
What he did to Job. Yeah, he had permission, but it's still a pretty nasty thing to do.
Helping the Antichrist to deceive people into worshiping him.
Desiring to "sift Peter as wheat," which most likely means he wanted to do the same things to Peter as he did to Job.
The Bible implies that he was behind Jesus crucifixion. If so, he was not only Hoist by His Own Petard but Out-Gambitted, because Jesus's death, preplanned by God, opened the one and only way for people to be saved.
In Revelation, he is pictured (probably metaphorically) as a red dragon sanding in front of a delivering woman so he can devour her child as soon as it is born.
Repeatedly trying to kill David, even after all the kindness and mercy he showed him.
Killing the priests of Nob who harbored David.
Almost getting his son Jonathan killed for not keeping Saul's foolish oath that he knew nothing about, and later deliberately trying to kill Jonathan for standing up for David.
Murdering some of the Gibeonites, whom Israel had sworn to protect. This one also applies to his household. This would come back to haunt the house of Saul when the Gibeonites forced David to hand over Saul's grandsons to be executed as the price of their allegiance.
Killing Absalom (David's son) explicitly against David's orders.
Killing Abner, who had defected to David.
Carrying out the Uriah Gambit. Joab had been a very naughty boy.
The Psalm David wrote in response to Jonathan's and Saul's death. As well as the enormousHeroic Blue Screen of Death he had when he learned about it.
The way David wept for Absalom, especially considering David would have lost his throne and possibly his life if Absalom had won.
Jesus' death. Even if you're not a Christian, you've gotta feel for the guy. Some of his miracles, too. Specially when he revived a poor little girl. And when he wept before he revived his old friend Lazarus.
2 Timothy. Knowing that he'll be executed soon, Paul urges Timothy, who he calls his son, to hurry to Rome so they can see each other before he, Paul, dies.
Ezra reading the book of the law in front of a crowd of truly repentant Jews.
Values Dissonance A point of contention for many, particularly in regard to the Old Testament.
The people of Israel behave this way every other chapter.
What Do You Mean, It Wasn't Made on Drugs?: Book of Revelation is pretty trippy, man. It's definitely the strangest and most surreal book in the Bible. Some people have suggested he was actually under the influence of volcanic fumes (like the Sibyl or the Oracle of Delphi). Others think he was simply trying to record events, places, beings, and substances he was shown but just could not understand.
