Matthew 24:30-31

30And then shall appear the sign of the Son of man in heaven; and then shall all the tribes of the land lament, and they shall see the Son of man coming on the clouds of heaven with power and great glory.

31And he shall send his angels with a great sound of trumpet, and they shall gather together his elect from the four winds, from [the one] extremity of [the] heavens to [the other] extremity of them.
