Matthew 24:30-31

30And at that time the sign of the Son of Man [coming in His glory] will appear in the sky, and then all the tribes of the earth [and especially Israel] will mourn [regretting their rebellion and rejection of the Messiah], and they will see the Son of Man coming on the clouds of heaven with power and great glory [in brilliance and splendor].

31And He will send His angels with a loud trumpet and they will gather together His elect (God’s chosen ones) from the four winds, from one end of the heavens to the other.
