Men's hearts failing them for fear, and for looking toward those things which are coming on the earth: for the powers of heaven shall be shaken.

The powers of heaven Some explain this of the angels, who shall be terrified and tremble at the sight of so many calamities. Others understand it of the heavenly bodies, the sun, moon, stars which shall in some sort, likewise, be confused in the general dissolution. The prophets often make use of such expressions, when speaking of the fall of monarchies, or the ruin of nations. The heavens shall be astonished and moved (Ezechiel xxxii. 7; Joel iii. 15.) (Calmet)
