Genesis 41:50

48And he gathered up all the food of the seven years, which were in the land of Egypt, and laid up the food in the cities: the food of the field, which was round about every city, laid he up in the same.

49And Joseph gathered corn as the sand of the sea, very much, until he left numbering; for it was without number.

50And unto Joseph were born two sons before the years of famine came, which Asenath the daughter of Potipherah priest of On bare unto him.

51And Joseph called the name of the firstborn Manasseh: For God, said he, hath made me forget all my toil, and all my father’s house.

52And the name of the second called he Ephraim: For God hath caused me to be fruitful in the land of my affliction.
