Genesis 41:49-52

And Joseph laid up grain as the sand of the sea, very much, until he left off numbering; for it was without number. And unto Joseph were born two sons before the year of famine came, whom Asenath, the daughter of Poti-phera priest of On, bare unto him. And Joseph called the name of the first-born Manasseh: For, said he, God hath made me forget all my toil, and all my father’s house. And the name of the second called he Ephraim: For God hath made me fruitful in the land of my affliction.
