Eve & Lilith

           According to midrashic literature, Adam's first wife was not Eve but a woman named Lilith, who was created in the first Genesis account. Only when Lilith rebelled and abandoned Adam did God create Eve.
           In an anonymous collection of midrashic proverbs probably compiled in the 11th century C.E., it is explained more explicitly that the conflict arose because Adam, as a way of asserting his authority over Lilith, insisted that she lie beneath him during sexual intercourse . Lilith, however, considering herself to be Adam's equal, refused, and after pronouncing the Ineffable Name (the magic name of God) flew off into the air. 

             Adam, distraught and no doubt also angered by her insolent behaviour, wanted her back. On Adam's request, God sent three angels, named Senoy, Sansenoy, and Semangelof, who found her in the Red Sea. Despite the threat from the three angels that if she didn't return to Adam one hundred of her sons would die every day, she refused, claiming that she was created expressly to harm newborn infants. However, she did swear that she would not harm any infant wearing an amulet with the images and/or names of the three angels on it.

             At this point, the legend of Lilith as the "first Eve" merges with the earlier legend of Sumero-Babylonian origin, dating from around 3,500 BCE, of Lilith as a winged female demon who kills infants and endangers women in childbirth.
