Mark 13:17 Meaning

15And let him that is on the housetop not go down into the house, neither enter therein, to take any thing out of his house:

16And let him that is in the field not turn back again for to take up his garment.

17But woe to them that are with child, and to them that give suck in those days!

18And pray ye that your flight be not in the winter.

19For in those days shall be affliction, such as was not from the beginning of the creation which God created unto this time, neither shall be.
