Matthew 24:23-27

23Then if any man shall say to you, Lo, here is Christ, or there; believe it not. 24For false Christs will arise, and false prophets, and shall show great signs and wonders; so that, if it were possible, they would deceive the very elect. 25Behold, I have told you before. 26Therefore if they shall say to you, Behold, he is in the desert; go not forth: behold, he is in the secret chambers; believe it not. 27For as the lightning cometh out of the east, and shineth even to the west; so shall also the coming of the Son of man be.
