Zohar: Samael and Lilith
The secret of secrets: From the strength of the noon-flame of Isaac (Geburah), from the wine lees, a naked shoot came forth, comprising together male and female, red like a lily, and they spread out on several sides, down several paths. The male is called "Samael," [literally: "the bitter beverage of God"] and his female [Lilith] is always included with him. Just as on the side of holiness there are male and female, so on 'the other side' there are male and female, included one with the other. The female of Samael is called 'snake,' 'a wife of harlotry,' 'the end of all flesh,' 'the end of days.' Two evil spirits are attached to one another. the male spirit is fine, the female spirit spreads out down several ways and paths, and is attached to the male spirit.
She dresses herself in finery like an abominable harlot and stands at the corners of streets and highways in order to attract men. When a fool approaches her, she embraces him and kisses him, and mixes her wine lees with snake poison for him. Once he has drunk, he turns aside after her. When she sees that he has turned aside after he from the way of truth, she takes off all the finery that she had put on for the sake of this fool.
This is the finery that she uses to seduce mankind: her hair is long, red like a lily; her face is white and pink; six pendants hang at her ears; her bed is made of Egyptian flax; all the ornaments of the East encircle her neck; her mouth is shaped like a tiny door, beautified with cosmetic; her tongue is sharp like a sword; her words smooth as oil; her lips beautiful, red as a lily, sweetened with all the sweetnesses in the world; she is dressed in purple, and attired in thirty-nine items of finery.
This fool turns aside after her, and drinks from the cup of wine, and commits harlotry with her, completely enamored of her. What does she do? She leaves him asleep on the bed and ascends to the realms above, accuses him, obtains authority, and descends. The fool wakes up, thinking to sport with her as before, but she takes off her finery, and turns into a fierce warrior, facing him in a garment of flaming fire, a vision of dread, terrifying both body and soul, full of horrific eyes, a sharpened sword in his hand with drops of poison suspended and dripping from it. He kills the fool, and throws him into Gehinnom [Klipoth, hell].
