In fact, unless those days were cut short, no flesh would be saved; but on account of the chosen ones those days will be cut short.”​—Matthew 24:21, 22.

But just what did Jesus mean when he spoke of “the disgusting thing that causes desolation . . . standing in a holy place”? What did he mean by the “great tribulation,” and by the “flesh” that was to be saved? Why would it be “on account of the chosen ones” that the tribulation would be “cut short”?

The fact that the “chosen” Christians no longer were in Jerusalem meant that God would not have to be concerned about their safety. They already had made their escape. God could thus allow the Romans to go into Jerusalem and speedily execute His judgment against the city. So on account of the chosen Christians’ already being out of Jerusalem, those days of tribulation came to an end more quickly, having been “cut short.” This allowed for some “flesh,” the 97,000, to survive.

That “great tribulation” in 70 CE was the most terrible calamity that ever came upon Jerusalem. It brought to a permanent end the Jewish-built city, its temple and the system of religion centered around it.
