~ Daniel 9:24-27 Explained in Chapters 10-11-12 ~
Dan. 10-11-12 is all one vision, and it builds on, expands, and explains in more detail what was given in Dan. 9:24-27 (the prophetic principle of "repeat and enlarge" that works all the way through the book from the beginning in Dan. 2).
Dan. 9:24-27 is basically about two points, actually ...two "desolations" (v.26):
1.) The "daily" desolation of the pagan Greek and pagan Roman empires (including the rest of the 70 final weeks of Jewish probation, and their rejection of the Messiah, which closed Jewish probation).
2.) The "desolation of abomination" of Papal Rome (until the "consummation" at the close of human probation just before Jesus' return).
The two Romes are the two "desolationS" (9:26) that oppress God's people through the "2520 or 7 Times."
Dan. 11:1-13 explains point #1 by giving the ongoing history of paganism (the first, or "daily" desolation, that began in 723 BC) starting with the Greeks in 331 BC and leading down to the formation of Pagan Rome (the King of the North) in about 200 BC (including the rest of the 70 weeks of Jewish probation, which ended when they rejected Jesus their "prince of the covenant" by giving Him to Pagan Rome in v. 14.)
Pagan Rome is the "robbers of thy people" in v. 14 who "establish the [whole] vision" of Chs. 10-12.
Dan. 11:14-30 explains the history of the "daily" desolation of paganism in Pagan Rome (including the crucifixion of Christ in v.22) up to the decree of Justinian in 533 AD, which made the Pope the new "king" of Europe (the new King of the North), or the "abomination of desolation."
Dan. 11:30-39 explains point #2 by giving the past history of the second "desolation," or the "abomination of desolation," or the first of the two phases of Papal Rome (the "wounded" and "healed" head of Rev. 13).
Dan. 11:40-45 explains 1798AD, and give future prophecy about what "healed" Modern Rome is in the process of doing right now, until human probation closes in Dan. 12:1.
Most of Dan. 12 is about what happened during the 1260 years of papal rule (the "abomination of desolation,") that ended in 1798 (at the end also of the 1260 and 1290), and about the "blessing" at the end of the 1335 days in 1843 (at the "Midnight Cry" of the Millerites) which led up to the ending of the 2520 days of "scattering" and the beginning of the time of "gathering" (that E.G. White described in Early Writings, p.74).
The Seventh-day Adventist Church was called into being at this time to warn and "gather" all God's children into one world-wide family, just before Satan's final attack with his Sunday Laws and Death Decree. Those who heed the warning SDAs give about the shortness of time (based on these prophecies in Daniel ....and the Revelation) and spiritually prepare themselves to resist the Pope's Sunday Law and Death Decree, will be saved eternally.
More about the two "desolations".....
Daniel prayed about them in Dan. 9:11...."the curse of Moses" (Lev. 28-26) that had come upon the followers of God, both Jews and Christians. The pagan part of the curse lasted 1260 years (723 BC to 538 AD), and the papal part of the same curse was another 1260 years (538 AD to 1798 AD), making a total of 2520 years of oppression on God's people. Since then the world has been in "the gathering time" described in Early Writings, p. 74.
