The Purpose of the Revelation and Future Conflict

Daniel 10:20-21

And he saith, Hast thou known why I have come unto thee? and now I turn back to fight with the head of Persia; yea, I am going forth, and lo, the head of Javan hath come;

but I declare to thee that which is noted down in the Writing of Truth, and there is not one strengthening himself with me, concerning these, except Michael your head.
