Mark 13:22 (KJV)

But woe to them that are with child, and to them that give suck in those days!

And pray ye that your flight be not in the winter.

For in those days shall be affliction, such as was not from the beginning of the creation which God created unto this time, neither shall be.

And except that the Lord had shortened those days, no flesh should be saved: but for the elect's sake, whom he hath chosen, he hath shortened the days.

And then if any man shall say to you, Lo, here is Christ; or, lo, he is there; believe him not:

But take ye heed: behold, I have foretold you all things.

But in those days, after that tribulation, the sun shall be darkened, and the moon shall not give her light,

And the stars of heaven shall fall, and the powers that are in heaven shall be shaken.

And then shall they see the Son of man coming in the clouds with great power and glory.

And then shall he send his angels, and shall gather together his elect from the four winds, from the uttermost part of the earth to the uttermost part of heaven.
