The correct answer to this open question is Ma'at.
Pharaos governed Egypt by the principle of order, truth, and justice which was collectively known as Ma'at.
In ancient Egypt, Ma'at was the representation of justice, truth, stability, and cosmic order. It represented the divine order in creation and all life. Ma'at is also the daughter of Ra, the Sun God for the Egyptians. The lessons of Ma'at taught humans to behave correctly, with respect and justice. Ma'at was also associated with the Nile flooding, so necessary to help agriculture and feed the Egyptians.
