Mark 13:17

15and let him who is on the housetop not go down, nor enter in, to take anything out of his house.

16Let him who is in the field not return back to take his cloak.

17But woe to those who are with child and to those who nurse babies in those days!

18Pray that your flight won’t be in the winter.

19For in those days there will be oppression, such as there has not been the like from the beginning of the creation which God created until now, and never will be.
