There are six points there that Daniel was told would happen in the 70 weeks:
1. "To finish the transgression"...which is accomplished in Israel crucifying their Messiah. Jesus said it on the cross..."IT IS FINISHED"...John 19:30
30 Therefore when Jesus had received the sour wine, He said, “It is finished!” And He bowed His head and gave up His spirit.
Israel had finished the transgression at that point...it ended the Old Covenant because God left the most holy place right after Jesus gave up His Spirit! Matthew 27:51
51 And behold, the veil of the temple was torn in two from top to bottom; and the earth shook and the rocks were split.
2. "To make and end of sin"
3. "To make atonement for iniquity"
4. "To bring in everlasting righteousness"
Those those three Hebrews makes clear Jesus accomplished...try Hebrews 9:11-14
11 But when Christ appeared as a high priest of the good things to come, He entered through the greater and more perfect tabernacle, not made with hands, that is to say, not of this creation;
12 and not through the blood of goats and calves, but through His own blood, He entered the holy place once for all, having obtained eternal redemption.
13 For if the blood of goats and bulls and the ashes of a heifer sprinkling those who have been defiled sanctify for the cleansing of the flesh,
14 how much more will the blood of Christ, who through the eternal Spirit offered Himself without blemish to God, cleanse your conscience from dead works to serve the living God?
See if you understand that. Christ IS our righteousness! We're also told that in 1 Corinthians 1:30, 31:
30 But by His doing you are in Christ Jesus, who became to us wisdom from God, and righteousness and sanctification, and redemption,
31 so that, just as it is written, “Let him who boasts, boast in the Lord.”
No Christian is righteous apart from Christ! Ever hear the term "Yahweh Tsikendu"? It means "THE LORD OUR RIGHTEOUSNESS!!!
5. "To seal up vision and prophecy"
Daniel was told to seal up his prophecy by Jesus in Daniel 12:7, who do you think the man dressed in linen is? I know many think it's Gabriel but it's not it's Christ! One can know this from Daniel 10:5!
6. "To Anoint the most holy place"
Christ did this just as the Hebrews 9:12 says:
12 and not through the blood of goats and calves, but through His own blood, He entered the holy place once for all, having obtained eternal redemption.
So what you call "rubbish" is what the bible teaches IF read properly.
This would be correct EXCEPT you want to discount what Paul said in Romans 9: 6-8:
6 But it is not as though the word of God has failed. For they are not all Israel who are descended from Israel;
7 nor are they all children because they are Abraham’s descendants, but: “through Isaac your descendants will be named.”
8 That is, it is not the children of the flesh who are children of God, but the children of the promise are regarded as descendants.
You see...you can't quote Romans 11 discounting what has been said in Romans 4:9-15 and Romans 9:6, 7...as well as the demonstration of the wild and natural olive tree becoming ONE given in Romans 11:17-24!!!
That is how all Israel is saved!!! If you need more...I've got more.
