The book of Daniel begins with six stories about Daniel and his three friends; these are found in the first six chapters of the book. Included in this section is the familiar story of Daniel in the lion’s den.
The last half of the book (chapters 7 to 12) contains four visions from God about the future. Because of this, the book of Daniel, along with the book of Revelation, is sometimes called an apocalyptic book, or book about the end times. These visions are easy to understand on a basic level, but their deeper meaning can be challenging to fully grasp.
