Luke 21:25–28 — signs in the heavens
[25] And there shall be signs in sun and moon and stars; and upon the earth distress of nations, in perplexity for the roaring of the sea and the billows; [26] men fainting for fear, and for expectation of the things which are coming on the world: for the powers of the heavens shall be shaken. [27] And then shall they see the Son of man coming in a cloud with power and great glory. [28] But when these things begin to come to pass, look up, and lift up your heads; because your redemption draweth nigh.
