Genesis 41:49-52

Joseph gathered very much grain, as the sand of the sea, until he stopped counting, for it was immeasurable. And to Joseph were born two sons before the years of famine came, whom Asenath, the daughter of Poti-Pherah priest of On, bore to him. Joseph called the name of the firstborn Manasseh: “For God has made me forget all my toil and all my father’s house.” And the name of the second he called Ephraim: “For God has caused me to be fruitful in the land of my affliction.”
