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.
