The Law of Carnal Commandments or the Torah of Carnal Commandments: The Law Moses and Zipporah gave Israel the second time was the same Torah, the same Priesthood as the first. However, because of the unrighteousness of the people, they could not understand what they were given. Without being in the Presence of God (Shekinah) they could not see the spiritual side of the Torah and only saw it was an earthly law.
