Genesis 41:45-50

45And Pharaoh called Joseph's name Zaphenath-paneah. And he gave him in marriage Asenath, the daughter of Potiphera priest of On. So Joseph went out over the land of Egypt.

46Joseph was thirty years old when he entered the service of Pharaoh king of Egypt. And Joseph went out from the presence of Pharaoh and went through all the land of Egypt.

47During the seven plentiful years the earth produced abundantly,

48and he gathered up all the food of these seven years, which occurred in the land of Egypt, and put the food in the cities. He put in every city the food from the fields around it.

49And Joseph stored up grain in great abundance, like the sand of the sea, until he ceased to measure it, for it could not be measured.

50Before the year of famine came, two sons were born to Joseph. Asenath, the daughter of Potiphera priest of On, bore them to him.
