Genesis 41:50-52

Before the years of famine came, two sons were born to Joseph by Asenath daughter of Potiphera, priest of On. Joseph named his firstborn Manasseh and said, “It is because God has made me forget all my trouble and all my father’s household.” The second son he named Ephraim and said, “It is because God has made me fruitful in the land of my suffering.”
