You are insisting that Gabriel's inspired prophecy was in error.
The 70 weeks/490 years are still running on; the wonderful promises concerning the Messiah were not fulfilled.
Even worse, Jesus' triumphant claim that the saving work given him by his Father was FINISHED was mistaken.
May I suggest that it is you who is in error, not Daniel, not Gabriel & not Jesus?
No, I am not saying what you say that I am saying. I am on my desktop at the moment so I can copy and paste and give a fuller answer since I am not very adept at doing that on my cell phone.
Daniel 9:24 (KJV) Seventy weeks are determined upon thy people and upon thy holy city, to finish the transgression, and to make an end of sins, and to make reconciliation for iniquity, and to bring in everlasting righteousness, and to seal up the vision and prophecy, and to anoint the most Holy.
The promises of Daniel 9:24 and others deal with restoring a sort of garden of Eden or ending evil on earth. Transgression is to be finished on earth; there is still transgression on earth. There is to be an end of sins; there are still sins on earth. There is to be everlasting righteousness on earth--there isn't.
Daniel 9:26 (KJV) And after threescore and two weeks shall Messiah be cut off....
Jesus was crucified and cut off. All of the good things are awaiting the Blessed Hope when the rest of the prophecy will be fulfilled by Jesus.
The return of Jesus:
Revelation 19:11-21 (KJV) And I saw heaven opened, and behold a white horse; and he that sat upon him [was] called Faithful and True, and in righteousness he doth judge and make war. His eyes [were] as a flame of fire, and on his head [were] many crowns; and he had a name written, that no man knew, but he himself. And he [was] clothed with a vesture dipped in blood: and his name is called The Word of God. And the armies [which were] in heaven followed him upon white horses, clothed in fine linen, white and clean. And out of his mouth goeth a sharp sword, that with it he should smite the nations: and he shall rule them with a rod of iron: and he treadeth the winepress of the fierceness and wrath of Almighty God. And he hath on [his] vesture and on his thigh a name written, KING OF KINGS, AND LORD OF LORDS. And I saw an angel standing in the sun; and he cried with a loud voice, saying to all the fowls that fly in the midst of heaven, Come and gather yourselves together unto the supper of the great God; That ye may eat the flesh of kings, and the flesh of captains, and the flesh of mighty men, and the flesh of horses, and of them that sit on them, and the flesh of all [men, both] free and bond, both small and great. And I saw the beast, and the kings of the earth, and their armies, gathered together to make war against him that sat on the horse, and against his army. And the beast was taken, and with him the false prophet that wrought miracles before him, with which he deceived them that had received the mark of the beast, and them that worshipped his image. These both were cast alive into a lake of fire burning with brimstone. And the remnant were slain with the sword of him that sat upon the horse, which [sword] proceeded out of his mouth: and all the fowls were filled with their flesh.
This is what it will be like when Daniel 9:24 is totally fulfilled:
Revelation 21:1-4 (KJV) And I saw a new heaven and a new earth: for the first heaven and the first earth were passed away; and there was no more sea. And I John saw the holy city, new Jerusalem, coming down from God out of heaven, prepared as a bride adorned for her husband. And I heard a great voice out of heaven saying, Behold, the tabernacle of God [is] with men, and he will dwell with them, and they shall be his people, and God himself shall be with them, [and be] their God. And God shall wipe away all tears from their eyes; and there shall be no more death, neither sorrow, nor crying, neither shall there be any more pain: for the former things are passed away.
