I found another bull/cow ritual that was like the other side of the coin of the red heifer sacrifice. It is very similar with the killing of an unblemished unyoked black bull, where they would take the skin and use it for the Kalu/Gala priests kettledrum. These drums were said to have special spiritual powers along with the Lyre. When I wrote the book on the Arch of Triumph from Palmyra I did a section on the Mesopotamian Lyre that they replicated and used at the first unvieling of the Arch. This too was said to have spiritual powers. I’m only showing you this to say that when the red heifer is burnt to ash, it to will carry a special spiritual thing with it. Obviously it is evil, but that should be obvious by now.
“The Gala (Sumerian: gala, Akkadian: kalû) were priests of the Sumerian goddess Inanna, significant numbers of the personnel of both temples and palaces, the central institutions of Mesopotamian city states, individuals with neither male nor female gender identities.”
