Matthew 24:5, 23-25

For many will come in my name, claiming, ‘I am the Messiah,’ and will deceive many.

At that time if anyone says to you, ‘Look, here is the Messiah!’ or, ‘There he is!’ do not believe it. For false messiahs and false prophets will appear and perform great signs and wonders to deceive, if possible, even the elect. See, I have told you ahead of time.
