Matthew 24:20

18Let him who is in the field not return back to get his clothes.

19But woe to those who are with child and to nursing mothers in those days!

20Pray that your flight will not be in the winter nor on a Sabbath,

21for then there will be great suffering, such as has not been from the beginning of the world until now, no, nor ever will be.

22Unless those days had been shortened, no flesh would have been saved. But for the sake of the chosen ones, those days will be shortened.
