Genesis 41:45-50

45And Pharaoh called Joseph's name Zaphnath-paaneah, and gave him as wife Asnath the daughter of Potipherah the priest in On. And Joseph went out over the land of Egypt.

46And Joseph was thirty years old when he stood before Pharaoh king of Egypt. And Joseph went out from Pharaoh, and passed through the whole land of Egypt.

47And in the seven years of plenty the land brought forth by handfuls.

48And he gathered up all the food of the seven years that was in the land of Egypt, and put the food in the cities; the food of the fields of the city, which were round about it, he laid up in it.

49And Joseph laid up corn as sand of the sea exceeding much, until they left off numbering; for it was without number.

50And to Joseph were born two sons before the year of famine came, whom Asnath the daughter of Potipherah the priest in On bore to him.
