Joseph might have come to Egypt during the reign of Sesostris II (1894-1878 BCE).
He most likely begins his career under Sesostris III (1878-1841 BCE). He lives in Egypt for 71 years, so Joseph dies in approximately 1805 BCE, under the reign of Amenemhet III (1841-1797 BCE).
Genesis 37 states that Joseph’s brothers sell him for 20 shekels of silver. That is the average price for a slave during the Middle Kingdom. Before that time, it is roughly 10-15 and later it became 30-40 shekels.
Joseph works as a slave, a practice that becomes widespread during the Middle Kingdom period. Many slaves are owned by private individuals, such as Potifar.
Genesis 41:14 states that before Joseph meets with Pharaoh, he puts on clean clothes and shaves. The Egyptians abhor facial hair and are a clean people.
