Matthew 24:16-22

16Then let them who are in Judaea flee to the mountains: 17Let him who is on the housetop not come down to take any thing out of his house: 18Neither let him who is in the field return back to take his clothes. 19And woe to them that are with child, and to them that nurse infants in those days! 20But pray ye that your flight may not be in the winter, neither on the sabbath: 21For then shall be great tribulation, such as hath not been since the beginning of the world to this time, no, nor ever shall be. 22And except those days should be shortened, there should no flesh be saved: but for the elect’s sake those days shall be shortened.
