21 for there shall be then great tribulation, such as was not from the beginning of the world till now, no, nor may be.

22 And if those days were not shortened, no flesh would have been saved; but because of the chosen, shall those days be shortened.

23 `Then if any one may say to you, Lo, here [is] the Christ! or here! ye may not believe;

24 for there shall arise false Christs, and false prophets, and they shall give great signs and wonders, so as to lead astray, if possible, also the chosen.

25 Lo, I did tell you beforehand.

26 `If therefore they may say to you, Lo, in the wilderness he is, ye may not go forth; lo, in the inner chambers, ye may not believe;
