Naamah or Na’amah (Hebrew: נעמה) is a legendary demonic creature, the mother of divination. How she became a demon is unclear.
Naamah comes from Hebrew: נעם naim and means pleasant.
The meaning of her name is argued among Hebrew scholars; it refers either to her virtuous nature (“pleasing” to God (YHVH)) or to a penchant for idolatry (singing “pleasant” songs to pagan idols).
In the Zohar
Naamah appears in the Zohar as one of the mates of the archangel Samael. She, along with Lilith, causes epilepsy in children. According to Zohar she is a succubus and fallen angel, and is generally regarded as an aspect or relation of Lilith.
After Cain killed Abel, Adam separated from Eve for 130 years. During this time, two female spirits, Lilith and Naamah would visit Adam and bear his children, who became the Plagues of Mankind. (Zohar 3:76b-77a)
Also according to Zohar, Naamah corrupted Aza and Azael. (Zohar: Genesis: Chapter 32)
