Genesis 41:50-52

Joseph had two sons born to him before the years of famine came. Asenath, daughter of Potiphera the priest of On, was their mother. Joseph named the firstborn Manasseh (Forget), saying, “God made me forget all my hardships and my parental home.” He named his second son Ephraim (Double Prosperity), saying, “God has prospered me in the land of my sorrow.”
