34 I tell you the truth, this generation will not pass away until all these things take place. 35 Heaven and earth will pass away, but my words will never pass away. 36 “But as for that day and hour no one knows it—not even the angels in heaven—except the Father alone. 37 For just like the days of Noah were, so the coming of the Son of Man will be. 38 For in those days before the flood, people were eating and drinking, marrying and giving in marriage, until the day Noah entered the ark.
When you see a person prophesying about the Messiah, you should know that he is either engaged in witchcraft, or has dealings with demons, or has adjured them with the Ineffable Name. Because such a sorcerer importunes the angels or the spirits, they say to him: 'Speak not in this manner, rather reveal the coming of the Messiah to the whole world.' But at the end he will be put to shame before the whole world, because he importuned the angels or the demons. And in its place misfortunes come because of him who adjured. And demons come and teach him calculations and secrets, to his shame and the shame of those who believe his words ... for no man knows about the coming of the Messiah.
