Tamiel is also called Kasdaye [also Kasdeja, י kaśdāy—”Chaldean”, “inhabitant of Chaldea”, “astrologer”] or Kasyade  in the Book of Enoch, Chapter 69.

Michael Knibb lists the translation of Tamiel as “God is Perfect” or “Perfection of God” [the combination of tamiym and El-God]. Tamiel was attributed as a teacher of astronomy [Enoch 8:7]. He also 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, [which is called] the son of the serpent named Taba’et [meaning male]” during the days of Noah, not the days of Jared
