flies in the face of what Paul wrote in Romans 11:25-25 where he prophetically stated that all of Israel would be saved after the 2,300 years of the heathen kingdom trampling the sanctuary of God and His earthly host had run it full course to completion.
I know it is confusing, but Romans 11 has nothing to do with Daniel 8's 2,300 day prophecy. Besides, you have 2,300 "years" when Daniel 8 is all about Greece,
before Rome conquered them and came into power. The 2,300 days is stated as "evenings and mornings," and just as in Genesis 1, evenings and mornings was a 1 day period, 24 hours, just under 7 years. That is why evenings and mornings was specified to show these are as they are written, and can't be turned into prophetic years. The time of the end was the end of Grecian rule over the world. The "little horn" of Daniel 8 is not the same "little horn" of Daniel 7. But they do show paradigms of three different 7 year periods. What you mentioned in Romans 11 is the last paradigm of the 7 year Great Tribulation when all of Israel will be saved. You are erroneously pulling aspects of different prophecies and combining them willy-nilly and even changing 7 years to 2300 years. Oy vey!
Daniel 8's period of 2300 literal days (6.3 years) is from 167 BC. to 160 BC (Jewish revolt) when in the middle of that period, just before 164 BC when Antiochus Ephiphanes IV died, he slaughtered a pig on the altar in the Jewish temple in honor of Zeus, defiling it. It was in the middle of the Maccebean revolt. Jacob Maccabees cleansed the temple.
Daniel 8:8 (Greece) Therefore the male goat grew very great (Alexander the Great); but when he became strong, the large horn was broken (died in his 30's), and in place of it four notable ones (his four generals) came up toward the four winds of heaven. 9 And out of one of them came a little horn (Antiochus Epiphanes IV) which grew exceedingly great toward the south, toward the east, and toward the Glorious
Land (Jerusalem)
.
This was a paradigm of the next Jewish revolt.
Daniel 9:26-27 shows another period of time after the death of Christ, which He, Himself, prophesied about the destruction of that period's Jewish temple by Rome. The prince is not Jesus but like another little horn Titus, and in the middle of the Jewish revolt of 66 AD to 73 AD, in 70 AD the temple was destroyed, defiling it. And the Jewish custom of burnt offerings in the temple was forever destroyed, finally putting an end to it as Jesus prophesied.
Daniel 7 is placed first and is a history of the Jews from the Babylonian captivity all the way to the second coming. It is similar to the great statue with the head of gold (Babylon), breast of silver (Medes and Persians), girdle of bronze (Greece) two legs of Iron (Rome), and feet and toes of mixture of iron and clay (strong and weak countries). The culmination is the period of the Great Tribulation and the little horn is the Antichrist. The paradigms of him prior to the end was Daniel 8 (Grecian antichrist) Antiochus Epiphanes IV, and Daniel 9 (Roman antichrist) Nero with his general Titus.
