17Let him which is on the housetop not come down to take any thing out of his house: 18Neither let him which is in the field return back to take his clothes. 19And woe unto them that are with child, and to them that give suck in those days! 20But pray ye that your flight be not in the winter, neither on the sabbath day:21For then shall be great tribulation, such as was not 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. 23Then if any man shall say unto you, Lo, here is Christ, or there; believe it not.
