Genesis 41:45-50

45Pharaoh gave Joseph the name Zaphenath-paneah,1 and he gave him Asenath daughter of Potiphera, priest of On,2 to be his wife. And Joseph took charge of all the land of Egypt.

46Now Joseph was thirty years old when he entered the service of Pharaoh king of Egypt. And Joseph left Pharaoh’s presence and traveled throughout the land of Egypt.

47During the seven years of abundance, the land brought forth bountifully. 48During those seven years, Joseph collected all the excess food in the land of Egypt and stored it in the cities. In every city he laid up the food from the fields around it. 49So Joseph stored up grain in such abundance, like the sand of the sea, that he stopped keeping track of it; for it was beyond measure.

50Before the years of famine arrived, two sons were born to Joseph by Asenath daughter of Potiphera, priest of On.
