Matthew 24:29-31

“Immediately after the distress of those days, the sun will be darkened, and the moon will not shed its light; the stars will fall from the sky, and the powers of the heavens will be shaken. Then the sign of the Son of Man will appear in the sky, and then all the peoples of the earth will mourn; and they will see the Son of Man coming on the clouds of heaven with power and great glory. He will send out his angels with a loud trumpet, and they will gather his elect from the four winds, from one end of the sky to the other.
