Mark 13:20-23

And except that the Lord had shortened those days, no flesh should be saved: but for the elect's sake, whom he hath chosen, he hath shortened the days. And then if any man shall say to you, Lo, here is Christ; or, lo, he is there; believe him not: for false Christs and false prophets shall rise, and shall shew signs and wonders, to seduce, if it were possible, even the elect. But take ye heed: behold, I have foretold you all things.
