In Matthew 24:3-5, the disciples came unto Jesus Christ privately, saying, Tell us, when shall these things be? and what shall be the sign of thy coming, and of the end of the age?
And Jesus answered and said unto them, TAKE HEED THAT NO MAN DECEIVE YOU. For many shall come in my name, saying, I am Christ; and shall deceive many.
In Matthew 24:11, 23-26, Jesus continues to warn the disciples, And many false prophets shall rise, and shall deceive many. Then if any man shall say unto you, Lo, here is Christ, or there; BELIEVE IT NOT. For there shall arise false Christs, and false prophets, and shall shew great signs and wonders; insomuch that, if it were possible, they shall deceive the very elect. Behold, I have told you before. Wherefore if they shall say unto you, Behold, he is in the desert; go not forth: behold, he is in the secret chambers; BELIEVE IT NOT.
