Matthew 24:21–25

For then there will be great tribulation, such as has not been from the beginning of the world until now, no, and never will be. And if those days had not been cut short, no human being would be saved. But for the sake of the elect those days will be cut short. Then if anyone says to you, ‘Look, here is the Christ!’ or ‘There he is!’ do not believe it. For false christs and false prophets will arise and perform great signs and wonders, so as to lead astray, if possible, even the elect. See, I have told you beforehand.

For at that time there will be great distress, the kind that hasn’t taken place from the beginning of the world until now and never will again. Unless those days were cut short, no one would be saved. But those days will be cut short because of the elect.

“If anyone tells you then, ‘See, here is the Messiah!’ or, ‘Over here!’ do not believe it. For false messiahs and false prophets will arise and perform great signs and wonders to lead astray, if possible, even the elect. Take note: I have told you in advance.

For there will be greater anguish than at any time since the world began. And it will never be so great again. In fact, unless that time of calamity is shortened, not a single person will survive. But it will be shortened for the sake of God’s chosen ones.

“Then if anyone tells you, ‘Look, here is the Messiah,’ or ‘There he is,’ don’t believe it. For false messiahs and false prophets will rise up and perform great signs and wonders so as to deceive, if possible, even God’s chosen ones. See, I have warned you about this ahead of time.

For at that time there will be great tribulation, such as has not happened from the beginning of the world until now, nor ever will happen. And unless those days had been shortened, no human being would be saved. But for the sake of the elect, those days will be shortened.

“At that time if anyone should say to you, ‘Behold, here is the Christ,’ or ‘Here he is,’ do not believe him! For false messiahs and false prophets will appear, and will produce great signs and wonders in order to deceive, if possible, even the elect. Behold, I have told you ahead of time!

For then shall be great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be. And except those days should be shortened, there should no flesh be saved: but for the elect’s sake those days shall be shortened. Then if any man shall say unto you, Lo, here is Christ, or there; believe it not. For there shall arise false Christs, and false prophets, and shall shew great signs and wonders; insomuch that, if it were possible, they shall deceive the very elect. Behold, I have told you before.
