What relationship did noblemen in ancient Egypt have with their pharaohs in ancient Egypt?

I can only answer for the period of the First Dynasty, when dynastic traditions were first starting. Of course, little is known for certain about that period since the hieroglyphic forms were just developing and not nearly as much has been unearthed from those times as compared with later dynasties.
From the very start, the early Kings (the word Pharaoh did not come about until later) understood that they needed noblemen to carry out various administrative tasks. Contrary to what many think, women, too, had legal rights and served as noblewomen to the King.

In my novels such relationships between the noblemen in service to their King is central to the plots, as there was much intrigue as well as smoothly functioning aspects to the Royal Court.
