Mark 13:18

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

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

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

19 For 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.

20 And except that the Lord had shortened those days, no flesh should be saved: but for the elect’s sake, whom he hath chosen, he hath shortened the days.

This was said to Israel at a particular time, so it is wise to read it together with the surrounding text. Do read the surrounding verses too, because the context often says more than a single verse.
