Matthew 24:30-31

30 And then at last, the sign that the Son of Man is coming will appear in the heavens, and there will be deep mourning among all the peoples of the earth. And they will see the Son of Man coming on the clouds of heaven with power and great glory. 31 And he will send out his angels with the mighty blast of a trumpet, and they will gather his chosen ones from all over the world—from the farthest ends of the earth and heaven.
