for then there will be great suffering, such as has not been from the beginning of the world until now, no, nor ever will be.
Context
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.
