"what will happen to your people in the future, for the vision concerns a time yet to come.”
Yes, I pointed that out, but it doesn't at all say what you think it says.
Dan 10:1
In the third year of Cyrus king of Persia a word was revealed to Daniel, who was named Belteshazzar. And the word was true, and it was a great conflict. And he understood the word and had understanding of the vision.
...
Dan 10:4
On the twenty-fourth day of the first month, as I was standing on the bank of the great river (that is, the Tigris)
Dan 10:5
I lifted up my eyes and looked, and behold, a man clothed in linen, with a belt of fine gold from Uphaz around his waist.
Dan 10:6 His body was like beryl, his face like the appearance of lightning, his eyes like flaming torches, his arms and legs like the gleam of burnished bronze, and the sound of his words like the sound of a multitude.
Dan 10:7 And
I, Daniel, alone saw the vision, for the men who were with me did not see the vision, but a great trembling fell upon them, and they fled to hide themselves.
Dan 10:8 So
I was left alone and saw this great vision, and no strength was left in me.
My radiant appearance was fearfully changed, and
I retained no strength.
Dan 10:9 Then
I heard the sound of his words, and as
I heard the sound of his words,
I fell on my face in deep sleep with my face to the ground.
Dan 10:10 And behold,
a hand touched me and set me trembling on my hands and knees.
Dan 10:11 And he said to me, “O Daniel, man greatly loved, understand the words that I speak to you, and stand upright,
for now I have been sent to you.” And
when he had spoken this word to me,
I stood up trembling.
Dan 10:12
Then he said to me, “Fear not, Daniel,
for from the first day that you set your heart to understand and humbled yourself before your God, your words have been heard, and
I have come because of your words.
Dan 10:13
The prince of the kingdom of Persia withstood me twenty-one days, but
Michael, one of the chief princes, came to help me, for I was left there with the kings of Persia,
Dan 10:14 and
came to make you understand what is to happen to your people in the latter days.
For the vision is for days yet to come.” (ESV)
So, Daniel was on the banks of a river on "the twenty-fourth day of the first month," "in the third year of Cyrus," with other men. He has a vision that no one else sees and it causes his appearance to change and he loses strength. Then, the angel touches him, causing him to tremble.
Notice then that the angel says, "for from the first day that you set your heart to understand and humbled yourself before your God,
your words have been heard, and
I have come because of your words." The angel
was sent to Daniel because of his words. That clearly is not going to happen at some point in the future; that would make no sense whatsoever. And the angel apparently had trouble with the prince of Persia and needed Michael's help,
to get to Daniel, so he could give him the revelation of the latter days.
In other words, the vision of the angel had already occurred to Daniel by the time he wrote about it. It makes no sense whatsoever for Daniel to say he had a vision of an angel on a specific day in the past, that others with him didn't see, but that the vision was going to occur in the future. The angel is clearly saying in v. 14 that the things he was about to reveal to Daniel in the rest of the vision (chapters 11-12), were what was going to happen in the future.
