What I am concerning about? the affair of Lord or mine own?

Daniel 9:20-27
While Daniel was speaking and praying confessing his sin and the sin of his people to the Lord for his holy hill- Messenger angel Gabriel told Daniel about the message and understand the vision: "Seventy sevens"
'Seventy sevens are decreed for people of Israel and the holy city to finish transgression, to put an end to sin, to atone for wickedness, to bring in everlasting righteousness, to seal up vision and prophecy and to anoint the most holy.
From the issuing of the decree to restore and rebuild Jerusalem until the Anointed One comes there will be sixty-nine 'sevens'. (Christ Jesus)
After the 69 sevens, the Anointed One will be cut off and will have nothing.
The people of ruler who will come will destroy the city and the sanctuary. He will confirm a covenant with many for one 'seven'. In the middle of the 'seven' he will put an end to sacrifice and offering. And on a wing of [the temple; the abominations] he will set up an abomination that causes desolation, until the end that is decreed is poured out on him.
Why?
God has ordained a period of 70x7 in which the salvation of his people will be completed. For the Jews, the number seven itself symbolized completeness, perfection. It may therefore be best to take the numbers symbolically, though the period of time between the decree to rebuild and restore Jerusalem and the beginning of Jesus' ministry comes very close to the 7+62 weeks = 483 days, standing for the same number of years. This is the total reached if we take the figures literally. (though there is more than one possible starting-point, and even the end-date is not absolutely fixed).
The ruler of people seems to point to the death and rejection of Christ and the destruction of the Temple which followed in AD 70 - with a wider reference at the end. But the subject of verse 27 is not at all clear. 'He' is taken by some to be the Messiah, by others to be the destroying prince of the previous verse.
In the 69 sevens there were 1)Messiah was cut off, have nothing 2) rebuilt holy city and sanctuary would be destroyed in AD 70, Rome destroyed Jerusalem.
How?
The time of under the hands of God, we do not know what the schedule of the Lord, but I should do my role in the world to honor the name of the Lord.
What I am concerning about, is my life? my living? my eating or financial problem, all of these the Lord will support me. This is my faith to the Lord!
