2 Peter 2:1
BUT there were false prophets among the people, as there will be false teachers also among you, who wickedly introduce damnable heresies, and deny the sovereign Lord who bought them, bringing on themselves swift destruction.
Revelation 2:20
Yet I have a few things against thee, because thou hast suffered that woman Jezabel, calling herself a prophetess, to teach, and to lead my servants into error, to commit whoredom, and eat the idol sacrifices.
Revelation 19:20
And the beast was seized upon, and with him the false prophet who performed the wonders before him, by which he deceived those who received the brand of the beast, and those who worshipped his image. They were both hurled alive into the lake of fire which burneth with brimstone.
