Genesis 41:49-52

Thus Joseph stored up grain in great abundance like the sand of the sea, until he stopped measuring it, for it was beyond measure. Now before the year of famine came, two sons were born to Joseph, whom Asenath, the daughter of Potiphera priest of On, bore to him. Joseph named the firstborn Manasseh, “For,” he said, “God has made me forget all my trouble and all my father’s household.” He named the second Ephraim, “For,” he said, “God has made me fruitful in the land of my affliction.”
