Matthew 24:22-28

22 Unless those days had been shortened, no flesh would have been saved. But for the sake of the chosen ones, those days will be shortened.

23 “Then if any man tells you, 'Behold, here is the Christ,' or, 'There,' don't believe it.  24 For there will arise false christs, and false prophets, and they will show great signs and wonders, so as to lead astray, if possible, even the chosen ones.

25 “Behold, I have told you beforehand.  26 If therefore they tell you, 'Behold, he is in the wilderness,' don't go out; 'Behold, he is in the inner chambers,' don't believe it.  27 For as the lightning comes forth from the east, and is seen even to the west, so will be the coming of the Son of Man.  28 For wherever the carcass is, there will the vultures be gathered together.
