Matthew 24:10-14, 24

At that time many will turn away from the faith and will betray and hate each other, and many false prophets will appear and deceive many people. Because of the increase of wickedness, the love of most will grow cold, but the one who stands firm to the end will be saved. And this gospel of the kingdom will be preached in the whole world as a testimony to all nations, and then the end will come.

For false messiahs and false prophets will appear and perform great signs and wonders to deceive, if possible, even the elect.
