That which Daniel wrote was prophecy; that is to say, guided by the divine power, he recorded long in advance the happenings of certain events, which of itself shows that this prophecy could not be understood until the events had transpired.

Daniel wrote concerning these events, but did not understand them.

They are set forth in his prophetic utterances recorded in the book of Daniel, chapters 7 to 12, inclusive.

Daniel himself said: "I heard, but I understood not: then said I, O my Lord, what shall be the end of these things?
And he said, Go thy way, Daniel; for the words are closed up and sealed till the time of the end.

Many shall be purified, and made white, and tried; but the wicked shall do wickedly: and none of the wicked shall understand; but the wise shall understand." (Daniel 12:8-10) The Lord had caused Daniel to record specifically what would happen when the time of the end should begin.
