We know that there must be a holy place, because Jesus said the abomination would be standing there. Matthew 24:15 There is no 'holy place' at the present time, so one must be anointed - and it takes 70 weeks (literally 490 days) to make this happen.
Dan 8
9Out of one of them came a little horn, which grew exceedingly great toward the south, toward the east, and toward the glorious land.
10It grew great, even to the host of heaven. And some of the host and some of the stars it threw down to the ground and trampled on them.
11It became great, even as great as the Prince of the host. And the regular burnt offering was taken away from him, and the place of his sanctuary was overthrown.
12And a host will be given over to it together with the regular burnt offering because of transgression,b and it will throw truth to the ground, and it will act and prosper.
The 'wicked prince of Israel' is one of the 'princes to come' and he confirms the covenant & breaks the covenant in the middle of 1 week (7 days). This is the placing of the abomination of desolation - by the 'wicked prince of Israel. (start of 1335 days) (Dec 17/ 18, 2020, is the covenant, 3.5 days later is Dec 21, 2020)
Because of this 'transgression', God punishes Israel (Jerusalem) on the 10th of Tevet, the seige of Jerusalem by the little horn, Mystery Babylon (Ezekiel 24:1-2) (10 Tevet, aka Dec 25, 2020) (presumably the Vatican). This is the 'peace & safety then sudden destruction', the start of the 'great tribulation'. That's why Jesus tells people in Judea to flee when they see the abomination standing in the holy place, - God via Babylon is going to punish them for it.
that 'wicked prince of Israel' (Ezekiel 21:25) is anointed after 7 + 62 weeks (69 weeks) after the 70 years of desolations of Jerusalem (Daniel 9:2) (April 19/ 20, 2018 aka 5 Iyyar, 5778)
It takes 69 weeks to get the anointed one/ 'messiah' of John 5:43, then 70 weeks to get a holy place where the abomination statue can be placed. Then the 1 week covenant is made, with the abomination going in the holy place 3.5 days later, in the middle of the 7 days, the start of 1335 days.
Dan 9
24 “Seventy weeks are decreed about your people and your holy city, to finish the transgression, to put an end to sin, and to atone for iniquity, to bring in everlasting righteousness, to seal both vision and prophet, and to anoint a most holy place.
[70 '7's means:
- 70 '7 years/ ie '77' years with the '7' years going from the 70th anniversary of Jerusalem, Israel to the 77th anniversary on May 13, 2025
- 70 times 7 years/ ie 490 years
- 70 times 7 days/ ie 490 days
25 Know therefore and understand that from the going out of the word to restore and build Jerusalem to the coming of an anointed one, a prince, there shall be seven weeks. Then for sixty-two weeks it shall be built again with squares and moat, but in a troubled time.
[this is the 7th head of Satan]
26 And after sixty-two weeks, an anointed one shall be cut off and shall have nothing. And the people of the prince who is to come shall destroy the city and the sanctuary. Its end shall come with a flood, and to the end there shall be war. Desolations are decreed.
[62 weeks later, this is where the 7th head receives his mortal head wound & resurrects. The 'prince to come' is the 8th head. Revelation 17:9-14]
27 And he shall make a strong covenant with many for one week, and in the middle of the '7' he shall put an end to sacrifice and offering. And on the wing of abominations shall come one who makes desolate, until the decreed end is poured out on the desolator.”
[It's not clear to me whether it is the 7th head or the 8th head that makes the 7 day covenant and places the abomination. If it is the 7th head, then the 8th head is the desolator (God's punishment for the abomination); if it is the 8th head that makes the covenant, then the false prophet is the desolator]
