Mark 13:19-23

19For those days will be a time of tribulation such as has not occurred 1since the beginning of the creation which God created until now, and never will. 20Unless the Lord had shortened those days, no 2life would have been saved; but for the sake of the 3elect, whom He chose, He shortened the days. 21And then if anyone says to you, ‘Behold, here is 4the Christ’; or, ‘Behold, He is there’; do not believe him; 22for false Christs and 5false prophets will arise, and will show 67signs and 8wonders, in order to lead astray, if possible, the elect. 23But take heed; behold, I have told you everything in advance.
