Mark 13:14, 19-20

“But when you see the abomination of desolation standing where he ought not to be ( let the reader understand), then let those who are in Judea flee to the mountains.

For in those days there will be such tribulation as has not been from the beginning of the creation that God created until now, and never will be. And if the Lord had not cut short the days, no human being would be saved. But for the sake of the elect, whom he chose, he shortened the days.
