Matthew 24:25

21 For at that time there will be great tribulation, unmatched from the beginning of the world until now, and never to be seen again.

22 If those days had not been cut short, nobody would be saved. But for the sake of the elect, those days will be cut short.

23 At that time, if anyone says to you, ‘Look, here is the Christ!’ or ‘There He is!’ do not believe it.

24 For false Christs and false prophets will appear and perform great signs and wonders that would deceive even the elect, if that were possible.

25 See, I have told you in advance.

26 So if they tell you, ‘There He is in the wilderness,’ do not go out; or, ‘Here He is in the inner rooms,’ do not believe it.

27 For just as the lightning comes from the east and flashes as far as the west, so will be the coming of the Son of Man.

28 Wherever there is a carcass, there the vultures will gather.

29 Immediately after the tribulation of those days: ‘The sun will be darkened, and the moon will not give its light; the stars will fall from the sky, and the powers of the heavens will be shaken.’
