Luke 21:25-27

25 "There will be signs in the sun, the moon, and the stars, and on the earth distress among nations confused by the roaring of the sea and the waves.
26 People will faint from fear and foreboding of what is coming upon the world, for the powers of the heavens will be shaken.
27 Then they will see "the Son of Man coming in a cloud' with power and great glory.
