Matthew 24:21-29 For then there shall be great tribulation, such as has not been since the beginning of the world until now, nor by any means shall be.

CAB⁽ⁱ⁾ ²¹ For then there shall be great tribulation, such as has not been since the beginning of the world until now, nor by any means shall be. ²² And unless those days were cut short, no flesh would be saved; but for the elect's sake, those days will be cut short. ²³ Then if someone says to you, 'Look, here is the Christ!' or 'There!' do not believe it. ²⁴ For false christs and false prophets will be raised up, and they will show great signs and wonders so as to deceive, if possible, even the elect. ²⁵ See, I have told you in advance. ²⁶ Therefore if they should say to you, 'Look, He is in the desert!' do not go out; or 'Look, He is in the inner rooms!' do not believe it. ²⁷ For as the lightning comes out from the east and flashes to the west, so shall also be the coming of the Son of Man. ²⁸ For wherever the carcass may be, there the eagles will be gathered together. ²⁹ "Immediately after the tribulation of those days, the sun shall be darkened, and the moon shall not give its light; and the stars shall fall from heaven, and the powers of the heavens shall be shaken.
