Matthew 24:19

then let those who are in Judea flee to the mountains.

Let him who is on the housetop not go down to take out the things that are in his house.

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

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

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.

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