Genesis 41:46-50

Now Joseph was thirty years old when he stood in the presence of Pharaoh, king of Egypt. And Joseph went out from the presence of Pharaoh and went through all the land of Egypt.

During the seven years of plenty the land produced abundantly.

So he collected 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 its own surrounding fields.

Joseph stored up grain in great abundance like the sand of the sea, until he stopped measuring it, for it was beyond measure. The Sons of Joseph

Now before the year of famine came, two sons were born to Joseph, whom Asenath, the daughter of Potiphera, priest of On, bore to him.
