Unlike Istehar, the pious maiden, Naamah, the lovely sister of Tubal-cain, led the angels astray with her beauty, and from her union with Shamdon sprang the devil Asmodeus.[11] She was as shameless as all the other descendants of Cain, and as prone to bestial indulgences. Cainite women and Cainite men alike were in the habit of walking abroad naked, and they gave themselves up to every conceivable manner of lewd practices. Of such were the women whose beauty and sensual charms tempted the angels from the path of virtue. The angels, on the other hand, no sooner had they rebelled against God and descended to earth than they lost their transcendental qualities, and were invested with sublunary bodies, so that a union with the daughters of men became possible. The offspring of these alliances between the angels and the Cainite women were the giants,[12] known for their strength and their sinfulness; as their very name, the Emim, indicates, they inspired fear. They have many other names. Sometimes they go by the name Rephaim, because one glance at them made one's heart grow weak; or by the name Gibborim, simply giants, because their size was so enormous that their thigh measured eighteen ells; or by the name Zamzummim, because they were great masters in war; or by the name Anakim, because they touched the sun with their neck; or by the name Ivvim, because, like the snake, they could judge of the qualities of the soil; or finally, by the name Nephilim, because, bringing the world to its fall, they themselves fell.[13] THE GENERATION OF THE DELUGE While the descendants of Cain resembled their father in his sinfulness and depravity, the descendants of Seth led a pious, well-regulated life, and the difference between the conduct of the two stocks was reflected in their habitations. The family of Seth was settled upon the mountains in the vicinity of Paradise, while the family of Cain resided in the field of Damascus, the spot whereon Abel was slain by Cain. Unfortunately, at the time of Methuselah, following the death of Adam, the family of Seth became corrupted after the manner of the Cainites. The two strains united with each other to execute all kinds of iniquitous deeds. The result of the marriages between them were the Nephilim, whose sins brought the deluge upon the world. In their arrogance they claimed the same pedigree as the posterity of Seth, and they compared themselves with princes and men of noble descent.[14]
