Matthew 24:24-31 (New International Version)

²⁴For false Christs and false prophets will appear and perform great signs and miracles to deceive even the elect—if that were possible. ²⁵See, I have told you ahead of time.

 ²⁶"So if anyone tells you, 'There he is, out in the desert,' do not go out; or, 'Here he is, in the inner rooms,' do not believe it. ²⁷For as lightning that comes from the east is visible even in the west, so will be the coming of the Son of Man. ²⁸Wherever there is a carcass, there the vultures will gather.

 ²⁹"Immediately after the distress 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 heavenly bodies will be shaken.'^[a]

 ³⁰"At that time the sign of the Son of Man will appear in the sky, and all the nations of the earth will mourn. They will see the Son of Man coming on the clouds of the sky, with power and great glory. ³¹And he will send 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.
