If as Dan. 9:25 reveals that it would be 69 Weeks or 483 years until the Messiah would arrive, and as many suggest it was Palm Sunday (the Triumphal Entry), and if therefore the Messiah was then Crucified on Thursday or Friday, you decide, then how do you account for the miscellaneous additional 4-5 days beyond Palm Sunday? Are you suggesting that God ‘approximated’ the prophetic Crucifixion of His Only Begotten Son, Yeshua Jesus? And did the Temple system and the Mosaic Law come to an ‘official’ end at that point, even though the Temple stood thirty some odd years afterwards?
After ministering in Israel for about 3 years, Jesus officially presented Himself to Israel as their Messiah on the first Palm Sunday. It was 483 years after Artazerxes Longimanus issued the decree to rebuild Jerusalem (Nehemiah 2). As He rode into the city Jesus pronounced His judgment upon the people for their failure to recognize the day of His coming (Luke 19:41-44). Daniel 9:25 said after that the Messiah would be executed and so He was.
By the end of that first Palm Sunday every minute of the 69th week had passed and the clock stopped. From that day to this, not one minute of the 70th week has transpired, nor will it until Israel is back in covenant with God. The crucifixion, the resurrection, and the entire church age have taken place in the pause between the 69th and 70th weeks.
The dispensation of Law has never ended. It was suspended when the clock stopped, and temple rituals and ceremonies ceased to be effective. Both the Letter to the Hebrews and Jewish history confirm this. Since that time the Lord has focused His attention on the Church. When He’s finished He will turn again to Israel to reinstate the Mosaic Law for the remaining seven years preceding the 2nd Coming. (Acts 15:13-18).
