In Egyptian mythology, Nehebkau ("he who harnesses the souls") was the snake god who guarded the entrance to Duat, the underworld. He also protected Re, the sun god, in his nightly forays through the underworld, as well as the pharaohs after they died. He also protected humans against bites from poisonous animals, especially snakes and scorpions.
Nehebkau (Nehebu-Kau, Nehebkhau), 'He Who Unites the Kas', was a benevolent snake god who the Egyptians believed was one of the original primeval gods.
In life, Nehebkau was invoked by the people to protect them from and cure them of venomous bites.
Nehebkau did not have a priesthood, but many people invoked him in magical spells to gain his protection and cures against snakebites.
