Where did the story of Lilith being Adam first wife come from?
“The Alphabet of Ben Sira is considered to be the oldest form of the story of Lilith as Adam’s first wife. Whether this certain tradition is older is not known. Scholars tend to date Ben Sira between 8th and 10th centuries. Its real author is anonymous, but it is falsely attributed to the sage Ben Sira. The amulets used against Lilith that were thought to derive from this tradition are in fact, dated as being much older.[36] The concept of Eve having a predecessor is not exclusive to Ben Sira, and is not a new concept, as it can be found in Genesis Rabbah. However, the idea that Lilith was the predecessor is indeed exclusive to Siria. According to Gershom Scholem, the author of the Zohar, R. Moses de Leon, was aware of the folk tradition of Lilith.
