'Pharaoh' is actually a Greek word that is based on an Egyptian word that meant 'great house'. When this word was first used, it referred to the palace of the king and its greatness, not just to the king himself. Today we use the word 'pharaoh' to refer to the ruler of ancient Egypt.
Pharaoh is the ruler of the solar plexus, the sun center in the subconscious mind. This is obscurity, or Egypt, to the conscious mind. Pharaoh's (the sun's) being in Egypt shows us that the light of the sun of righteousness is veiled by our life on the lower or sense plane. The pharaoh was the political and religious leader who held the titles: 'Lord of the Two Lands' and 'High Priest of Every Temple'. As 'Lord of the Two Lands' the pharaoh was the ruler of Upper and Lower Egypt.
