Once the author gets past its own time and tries to make genuine predictions it fails. Daniel was written while the revolt was still going on. The final "week" was the period from the assassination of Onias (171 BCE) to when Daniel thought the world would end in 164. Antiochus put a statue of Zeus in the Jerusalem Temple in 168 BCE (halfway into Daniel's last week). The author knows about these events, but everything he predicts after that failed to come true. Daniel says that Aniochus would conquer Egypt, come back to Palestine and finally be conquered by the angel Michael. Obviously, none of that happened. If the book isnt deceptive, than it is at least wrong. The author also has:
- Numerous historical errors and anachronisms. The book starts by claiming that Jerusalem fell in the third year of King Jehoiakim. This contradicts all known historical evidence, including the timeline from Jeremiah. There are also a number of indications that the author confused Nebuchadrezzar with Nabonidus. One of the more important characters from the book, Darius the Mede, is totally unknown to history and appears to be either a complete fabrication or a conflation of several other people.
- The succession of nations in the book appears to be wrong. According to Daniel, it was Babylon, Media, Persia and Greece. In reality, Media fell to Persia about 15 years before the fall of Babylon.
- There is ample evidence from the text that the author expected the Greek Seleucid king Antiochus IV to be the catalyst that sparked the final battle between God and ad his enemies. The author expected that this battle would end with the the destruction of the earthly system and the institution of the literal Kingdom of God.
- When read in context, all of Daniel's prophecies point to Antiochus IV. The author thus expected him to be the last King of the Seleucid line, and that the 'time of the end' would therefore be about 164 BC.
- The book of Daniel is totally unknown prior to about 150 BC. There are a number of lists of books considered sacred by the Jews - Daniel is not among them.
Jesus uses the "Son of Man" figure in Daniel 7 to describe himself: https://www.biblegateway.com/passage/?search=Daniel+7&version=NIV
“In my vision at night I looked, and there before me was one like a son of man,[a] coming with the clouds of heaven. He approached the Ancient of Days and was led into his presence. 14 He was given authority, glory and sovereign power; all nations and peoples of every language worshiped him. His dominion is an everlasting dominion that will not pass away, and his kingdom is one that will never be destroyed.
Why should we take the NT authors seriously with this considered?
