\This chapter begins in the third year of Darius, the Mede, or Cyrus, King of Persia only a few years before Daniel’s death. According to Ezra 2:64, 42,360 Jews had had already returned to Jerusalem after the decree by King Cyrus.
Everything written in this chapter, like the rest of prophecy, affects the Jews first and then the rest of the world. As Daniel was told in chapter 10, this is “what will happen to your people in the latter days, for the vision refers to many days yet to come” (Daniel 10:14).
