Mark 13:19-21

New Matthew Bible

¹⁹ For there shall be in those days such tribulation as was not from the beginning of creatures that God created to this time, nor will be again. ²⁰ And if the Lord did not shorten those days, no one would be saved. But for the sake of the elect, whom he has chosen, he has shortened those days.

²¹ And then if anyone says to you, Lo, here is Christ! Lo, he is there! –  believe it not.
