Matthew 24:17

14 and this good news of the reign shall be proclaimed in all the world, for a testimony to all the nations; and then shall the end arrive.

15 `Whenever, therefore, ye may see the abomination of the desolation, that was spoken of through Daniel the prophet, standing in the holy place (whoever is reading let him observe)

16 then those in Judea -- let them flee to the mounts;

17 he on the house-top -- let him not come down to take up any thing out of his house;

18 and he in the field -- let him not turn back to take his garments.

19 `And wo to those with child, and to those giving suck in those days;

20 and pray ye that your flight may not be in winter, nor on a sabbath;
