29 "Immediately after the tribulation of those days, the sun will be darkened, and the moon will not give its light, and the stars will fall from the heaven, and the powers of the heavens will be shaken.*‘Stars’ often refer to angels, in the Scriptures, and "the powers of the heavens" most probably refers to high ranking fallen angels. It is at this time that Satan will be confined in the Abyss (Revelation 20:1-3). (Just one literal star hitting the earth would reduce it to dust, so the reference cannot be to them.) 30 And then the sign of the Son of the Man will appear in the sky, and then all the tribes of the earth will mourn*Literally, ‘beat the breast’—in Semitic cultures this action expresses strong emotion, involving some combination of grief, fear and despair. This will be the attitude of everyone who is wearing the ‘mark’.—they will see the Son of the Man coming on the clouds of the heaven with power and great glory. 31 And He will send out His angels with a great sound of a trumpet and they will collect His elect from the four winds, from one extreme of the heavens to the other.
