Matthew 24:15-22

When therefore ye see the abomination of desolation, which was spoken of through Daniel the prophet, standing in the holy place (let him that readeth understand), then let them that are in Judæa flee unto the mountains: let him that is on the housetop not go down to take out the things that are in his house: and let him that is in the field not return back to take his cloak. But woe unto 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, neither on a sabbath: for then shall be great tribulation, such as hath not been from the beginning of the world until now, no, nor ever shall be. And except those days had been shortened, no flesh would have been saved: but for the elect’s sake those days shall be shortened.
