Luke 21:25-27

And there shall be signs in the sun and in the moon and in the stars; and upon the earth distress of nations, by reason of the confusion of the roaring of the sea, and of the waves:

Men withering away for fear and expectation of what shall come upon the whole world. For the powers of heaven shall be moved.

And then they shall see the Son of man coming in a cloud, with great power and majesty.
