Did the 7th Trumpet sound at the week of the Cross as well, and Jesus became the King over every nation? Revelation 10:6-7
No.
The 7th Trumpet declares time is finished.
There's nothing preventing us from interpreting "time" here as "
prophetic time" and not chronological time in general - because at some point after "time no more" the
days of the 7th trumpet come to pass.
You can't have "time no more" followed "days" which we all know are blocks of time.
On the Cross, time was not finished. The work of redemption was finished, but the time and mystery of the redemption extended to the Gentiles was just starting. Jesus would not be the King of Israel, until the fulness of the Gentiles was brought in.
When trying to understand what "to finish, make and end, make recon, bring in, seal up, and anoint" pertains to,
we cannot look beyond what Gabriel says these pertain to: "thy people and thy holy city" aka ancient Israel and Jerusalem. Today, God's people are the "Israel of God" who "walk by this rule" of the "new creature" in Christ. Abraham's seed today are those who belong to Christ, etc.
Therefore, we can't say "sin still exists in the world so the prophecy is still future..."
The prophecy was sealed, not declared fulfilled.
One of the reasons why the 70 Weeks was cut off from the 2,300 Days was "to seal up the vision and the prophecy" - which refers to a "seal of assurance" for Daniel's people that the 2,300 Days would just as surely come to pass as when they would see the 70 Weeks come to pass and the Gospel go to the Gentiles.
Jesus put in the work to end the transgression, but the transgression was still in effect until the Second Coming.
Again, "thy people and thy holy city".
Jesus put in the work to bring in eternal righteousness,
After the Cross, Jesus directed the apostles to only go to the "lost sheep of the house of Israel" and many found "eternal righteousness" in Christ. Again, "thy people and thy holy city".
Jesus sealed up the prophecy about the Prince to come, because the Prince to come part is the Second Coming.
The 70 Weeks stretch from 457 B.C. to 34 A.D. which pertains to His First Coming.
Jesus was the anointed, that is what Messiah means.
Yes, because of Daniel's confusion, the 70 Weeks were "cut off" from the 2,300 in order to clarify what the 2,300 did not: the timing of the arrival of the "anointed One" - as well as the details of His mission - through Whom He would accomplish the "cleaning of the sanctuary" after 2,300 Days mentioned in chapter 8.
However the disclaimer after the promises would be that the Messiah would be cut off, and then they would have to wait for the Prince to come, the Second Coming.
Actually, before any mention of the Messiah at all, the prophecy mentions the six reasons for why the 70 was cut off from the 2300 - one of which is "to anoint the Most Holy" in the Jordan.
Jesus fulfilled the Messiah half for 3.5 years. Jesus will finish the King half in a future 3.5 years.
I'm glad you recognize what many don't: that we can't slice off the entire 70th week if the Cross has half of it nailed down firmly in history. However, we don't have any good reason to slice off 3.5 years either, because:
1) no other Numerically Specific Time Prophecy utilizes a "gap" - their duration lasts only as long as stated
2) Jesus is easily the "prince that shall come", "covenant confirmer", "sacrifice/oblation suspender, etc.
3) only Jesus can fulfill the prophecy: for instance, Job says Leviathan (Satan) makes covenants with no one
The final minutes of the 70th week could be an hour.
Actually, the final minutes of the 70 Weeks pertained to "thy people and thy holy city" back then, seemingly with the stoning of Steven, because right after the Gospel went to the Gentiles.
Jesus is the 70th week, not a literal fixed time period of 7 years Gabriel never said the 70th was a set of seven. Gabriel implies the Messiah and Prince to come is the 70th week.
If the 70th Week is as much a block of time on the prophetic timeline as are the 69 Weeks - the 70th Week isn't "Jesus" but "a period in which Jesus would accomplish His mission".
Daniel 9:27 is a set of days, the days of the 7th Trumpet.
The 7 Churches, Seals, Trumpets being parallel to one another on the prophetic timeline, the 7th trumpet began sounding in 1844 and will continue to sound until "the Trump of God" is blown by Him.
