Kasdeja (from Heb. כַּשְׂדַּי — "inhabitant of Chaldea") or Kasyade (prob. compd. of כסה kasah — "to conceal" + יד yad — "hand, power"; lit. "covered hand", "hidden power") is a fallen angel in the Book of Enoch, Chapter 69. Kasdeja taught "the children of men all of the wicked strikes of spirits, [the strikes of] demons, and the strikes of the embryo in the womb so that it may pass away (abortion), and [the strikes of the soul], the bites of the serpent, and the strikes which befall through the noontide heat. [He is called] the son of the serpent named Taba'et (meaning male)".
