24:29 “Immediately 1 after the suffering 2 of those days, the sun will be darkened, and the moon will not give its light; the stars will fall from heaven, and the powers of heaven will be shaken. 3 24:30 Then 4 the sign of the Son of Man will appear in heaven, 5 and 6 all the tribes of the earth will mourn. They 7 will see the Son of Man arriving on the clouds of heaven 8 with power and great glory. 24:31 And he will send his angels with a loud trumpet blast, and they will gather his elect from the four winds, from one end of heaven 9 to the other.
[24:29] 3 sn An allusion to Isa 13:10, 34:4 (LXX); Joel 2:10. The heavens were seen as the abode of heavenly forces, so their shaking indicates distress in the spiritual realm. Although some take the powers as a reference to bodies in the heavens (like stars and planets, “the heavenly bodies,” NIV) this is not as likely.
