Matthew 24:20-22

King James Version

²⁰ But pray ye that your flight be not in the winter, neither on the sabbath day:

²¹ For then shall be great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be.

²² And except those days should be shortened, there should no flesh be saved: but for the elect's sake those days shall be shortened.
