So, when Jesus said,
"When ye therefore shall see
the abomination of desolation, spoken of by Daniel
stand in the holy place,
let him understand: Then let them which be in Judaea
flee into the mountains:"
At the time of Jesus Christ,
the Temple was the holy place.
After Jesus went to heaven, there was no holy place but only
in the life of the belivers.
At the time Jesus said that,
the people knew he was talking about the Temple,
so the abomination of desolation stood in the holy place
during the 70 week
So why the space between the 69 and 70 weeks?
Making a new Temple is not going to make it holy.
Only when Jesus comes back to earth will a new Temple
become a holy place.
After the great battle Armageddon the people come from
the cities to clean up the mess, not the mountains.
"And they that dwell in the cities of Israel shall go forth, and
shall set on fire and burn the weapons, both the shields and
the bucklers, the bows and the arrows, and the handstaves,
and the spears, and they shall burn them with fire seven years:"
