The lyrics are dark, some from Bible and Talmud references. It is at timls simple and melodic, and others more complex with a driving dance able bet. I have here a few examples YouTube.
Song for Samael
In Jewish lore, Samael is said to be the angel of death, the chief ruler of the Fifth Heaven and one of the seven regents of the world served by two million angels; he resides in the Heaven. Yalkut I, 110 of the Talmud speaks of Samael as Esau's guardian angel. InSotah10b, Samael is Esau's guardian angel, and in the Sayings of Rabbi Eliezer, he is charged with being the one who tempted Eve, then seduced and impregnated her with Cain. Though some sources identify Gadreel as the angel that seduced Eve, other Hebrew scholars say that it was Samael who tempted Eve in the guise of the Serpent. Samael is also sometimes identified as being the angelic antagonist who wrestled with Jacob, and also the angel who held back the arm of Abraham as he was about to sacrifice his son.
