Daniel prophesies to the Jews about Antiochus (called the Noble), who will plague them, yet he describes Antiochus in a way that also foreshadows the Antichrist and the end times. Antiochus's reign is depicted as shameless and violent, with the impious worshiping him as if he were Christ. In the turmoil, believers can find peace in Jesus Christ, our deliverer.
Chapter 12 focuses entirely on the Antichrist and the last times. Daniel, though told he won't understand all he's seen, is advised to live faithfully, avoiding endless speculation about God's timing (see Acts 1:7). The central message is that God's wisdom and kingdom will ultimately prevail. Verses 11-12 may refer to three possible events: (1) the desecration of the temple by Antiochus in 167 BC, (2) the destruction of the temple by the Romans in AD 70, or (3) a future abomination by the Antichrist.
The mentioned days (1,290 and 1,335) likely relate to one of these events, although their specific significance is unclear. God's promise to bless those who endure applies to believers of all ages. The discourse ends with the assurance that Michael protects Israel, and the faithful will rise to everlasting life. Rather than trying to predict the end, Daniel is advised to "go your way"--trusting in God's promise of eternal life. May we do the same.
