The word “Lilith” appears in the Bible only once, in Isaiah 34:14, which the King James Version translates as “screech owl.” The word “lilith” may mean night creature, related to the Hebrew layla. Her Sumerian roots as a demonic infant-killer long antedate the Bible, but her developed “Jewish” personality came to the fore barely 1,000 years ago in the Alphabet of Ben Sira. Lilith is often interpreted as representing the sexual (as opposed to maternal) side of Eve.
