Matthew 24:16-28

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. Then if any man shall say unto you, Lo, here is the Christ, or, Here; believe it not. For there shall arise false Christs, and false prophets, and shall show great signs and wonders; so as to lead astray, if possible, even the elect. Behold, I have told you beforehand. If therefore they shall say unto you, Behold, he is in the wilderness; go not forth: Behold, he is in the inner chambers; believe it not. For as the lightning cometh forth from the east, and is seen even unto the west; so shall be the coming of the Son of man. Wheresoever the carcase is, there will the eagles be gathered together.
