Genesis 41:50-52

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.”
