Mark 13:6

"For false Christs and false prophets shall rise, and shall shew signs and wonders, to seduce, if it were possible, even the elect."

"I am come in my Father's name, and ye receive me not: if another shall come in his own name, him ye will receive."

"Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world."

"I said therefore unto you, that ye shall die in your sins: for if ye believe not that I am he, ye shall die in your sins."

"For many shall come in my name, saying, I am Christ; and shall deceive many."

"And many false prophets shall rise, and shall deceive many."

"Then the LORD said unto me, The prophets prophesy lies in my name: I sent them not, neither have I commanded them, neither spake unto them: they prophesy unto you a false vision and divination, and a thing of nought, and the deceit of their heart."
