Luke 21:26

New English Translation

²⁶People will be fainting from fear^[a] and from the expectation of what is coming on the world, for the powers of the heavens will be shaken.^[b]

Luke 21:26 tn According to L&N 23.184 this could be mainly a psychological experience rather than actual loss of consciousness. It could also refer to complete discouragement because of fear, leading people to give up hope (L&N 25.293).
Luke 21:26 sn An allusion to Isa 34:4. 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.
