The Book of Daniel takes place during Babylon's conquest of Judah. The young males are shipped off to Babylon to be reeducated, and Daniel and his friends promise to stay faithful to each other and to God as they are taken into enemy territory. Their blessings from the Lord earn them the favor from the kings, but also make them many enemies in the court.

The Protestant canon version of Daniel is twelve chapters long. The Story of Susannah, The Idol Bel and the Dragon, and The Song Of The Three Children (which are deuterocanonical books) are all adapted from the Vulgate version of Daniel, which extended the chapter count to fourteen.
!!This book provides examples of:

* AGodAmI:
** Nebuchadnezzar reflects on the splendor of his city and how he built it all. God responds to his pride by temporarily driving the king insane and causing him to think he's an animal.
** Darius is encouraged to sign an edict saying that for the thirty days only he may be prayed to.
* AttemptedRape: Susanna is nearly assaulted by two elderly men who were so smitten by her beauty that they tried to rape her while she was alone taking a bath. They end up accusing her of having improper relations with somebody else that they witnessed when they bring her before the judges.
* BatmanGambit: The officials that give Darius said decree count on Daniel being too faithful to stop praying to his God, even in secret.
* BringMyBrownPants: In some translations, King Belshazzar of Babylon became so frightened of the hand writing on the wall the PortentOfDoom that he urinated in his robes.
* ClearMyName: The story of Daniel saving Susannah's honor from two false accusers.[[labelnote:*]]Although Protestants consider this chapter (13) to be part of the Apocrypha, and tend to omit it.[[/labelnote]]
* DepravedHomosexual: Daniel 11:37, which is commonly attributed to TheAntichrist by some Christian Bible students, is sometimes interpreted as the person it's talking about being this due to how some translations handle the verse.
-->''He shall regard neither the gods of his fathers, nor the desire of women, nor regard any god; for he shall magnify himself above them all.''
* EarlyBirdCameo: Nebuchadnezzar seeing what looks like "a son of the gods" inside the furnace has been theorized in traditional Christian interpretation to be an early appearance of Jesus. Daniel later meets with a "son of man" sent from heaven, who Christ identifies himself as in the Gospels.
* {{Foreshadowing}}: Daniel 9:24-26 is believed to be talking about the coming of Jesus Christ in most Christian interpretations, with verse 27 referring to the coming of TheAntichrist.
* ForgotICouldChangeTheRules: Averted. Even the king cannot annul his own decrees once they are passed. This causes a problem when he's tricked into passing a law that ends up ordering the death of his favorite advisor Daniel.
* GainaxEnding: The first half of the book chronicles the adventures of Daniel and his friends in Babylon. The latter half of the book is about visions Daniel receives of the future, which get just as odd as the Literature/BookOfRevelation.
* HoistByHisOwnPetard: Darius's advisors trick him into ordering Daniel to be thrown into a den of lions. When Daniel is found alive, Darius orders those same advisors to be thrown to the lions instead.
* HonorBeforeReason: Several times by the protagonists, even when their life is on the line. When ordered to bow to a large statue, the three friends refuse to bow. When told that praising God and not the king will be punished with death, Daniel openly prays anyway and is arrested.
* KeepTheReward: When Daniel was called by King Belshazzar of Babylon to interpret the writing on the wall in chapter 5, promising to reward him by even making him "the third ruler of the kingdom", Daniel tells the king to give the reward to someone else, yet he will interpret the writing. Daniel still gets rewarded, though it doesn't last for very long as the message for the king from the writing on the wall was fulfilled that very night.
* ManOnFire: The guards who put Shadrach, Meshach, and Abednego into the furnace were consumed by the flames as they threw the three captives in. Fortunately, the "fourth man" in the furnace (interpreted by Christians as a pre-incarnate version of Jesus) protected the three Jews in the flames so they came out looking no worse for wear as when they went in.
* MeaningfulRename: The Hebrew boys are all given Chaldean names, to enforce their assimilation into Babylonian culture. Yet Daniel is the only character of the four who is still referred to by his original name in the narration.
* MusicalEpisode: Daniel chapter 3 in Catholic editions feature the Song Of The Three Children, also known as the Prayer of Azariah.
* PortentOfDoom: The "writing on the wall" that King Belshazzar had Daniel translate -- ''Mene, mene, tekel, u-Pharsin'' -- meant that his kingdom was going to come to an end. And surely enough, it was fulfilled on the very same night.
* TrueCompanions: Daniel (Belteshazzar), Hananiah (Shadrach), Mishael (Meshach), and Azariah (Abednego).
* [[UpToEleven Up To Seven]]: When the three friends deny their second chance to bow to the golden statue, Nebuchanezzer orders for the furnace they're to be thrown in to be heated seven times hotter than usual.
* WhatTheHellHero: When Nebuchadnezzar has a dream he wishes his magicians to interpret, he decides to test their truthfulness by declaring he will not tell them what his dream was, ''they must tell him''. Knowing that lying would be suicide, the magicians angrily respond that this is impossible and no one but the gods can do this. The king orders them to be all executed.
** Perhaps Nebuchadnezzar was on to something. If the gods of the magicians were real, they would already know the details of the king's dream. As it turns out, Daniel and his three friends interpret the dream having been told by God himself.
* YourDaysAreNumbered: The PortentOfDoom which Daniel translated for King Belshazzar of Babylon told him his days and his kingdom were about to end soon.
