Matthew 24:27

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.’

30 At that time the sign of the Son of Man will appear in heaven, and all the tribes of the earth will mourn. They will see the Son of Man coming on the clouds of heaven, with power and great glory.

31 And He will send out His angels with a loud trumpet call, and they will gather His elect from the four winds, from one end of the heavens to the other.
