I found this information about Egypt in Joseph's time interesting.
WHEN DID JOSEPH ARRIVE?All quoted material is from "Life Application Study Bible." See the sidebar under "Bible Study: Genesis" for links to references used.
The date of Joseph's arrival in Egypt is debatable. Many believe he arrived during the period of the Hysksos rulers, foreigners who came from the region of Canaan. They invaded Egypt and controlled the land for almost 150 years. If Joseph arrived during their rule, it is easy to see why he was rapidly promoted up the royal ladder. Because the Hysksos were foreigners themselves, they would not hold this brilliant young foreigner's ancestry against him.
Pharaoh was the general name for all the kings of Egypt. It was a title like "King" or "President" used to address the country's leader. The Pharaohs in Genesis and Exodus were different men.
THE GOOD LIFE IN EGYPT
Ancient Egypt was a land of great contrasts. People were either rich beyond measure or poverty stricken. There wasn't much middle ground. Joseph found himself serving Potiphar, an extremely rich officer in Pharaoh's service. Rich families like Potiphar's had elaborate homes two or three stories tall with beautiful gardens and balconies. They enjoyed live entertainment at home as they chose delicious fruit from expensive bowls. They surrounded themselves with alabaster vases, paintings, beautiful rugs, and hand-carved chair. Dinner was served on golden tableware, and the rooms were lighted with gold lampstands. Servants, like Joseph, worked on the first floor, while the family occupied the upper stories.
