In the esoteric teachings of Egyptian priests, particularly in the ancient texts from the 11th and XII dynasties (refer to the Book of the Dead), there seemed to be an expression of the pure monotheistic doctrine, albeit veiled in allegories and symbols to obscure understanding from the masses. However, during the XV dynasty and possibly influenced by Turanian ideologies, this concept seems to have diminished. If the priests maintained it, it was likely in a manner reminiscent of the philosophical schools of Greece and Sicily, shrouded in a grave secrecy and unshared with others.
It is noteworthy that the enlightened Pharaohs of the XII dynasty, who were blessed by Patriarch Jacob, seemingly aligned themselves more closely with the class of sages and high priests, likely recognizing the One true God. The very acknowledgment of Joseph as a wise man serves as evidence of this (see Genesis 41 and the concluding chapter).
