Matthew 24:30-31

And 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]. [Dan 7:13; Rev 1:7] And 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. [Is 27:13; Zech 9:14]
