Genesis 48:1-5

Now some time after these things happened, Joseph was told, “Your father is sick.” So he took his two sons Manasseh and Ephraim with him [to go to Goshen]. And when Jacob (Israel) was told, “Look now, your son Joseph has come to you,” Israel strengthened himself and sat up on the bed. Then Jacob said to Joseph, “God Almighty appeared to me at Luz (Bethel) in the land of Canaan and blessed me, and said to me, ‘Behold, I will make you fruitful and numerous, and I will make you a great company of people, and will give this land to your descendants after you as an everlasting possession.’ [Gen 28:13-22; 35:6-15] Now your two sons [Ephraim and Manasseh], who were born to you in the land of Egypt before I came to you in Egypt, are mine; Ephraim and Manasseh shall be mine [that is, adopted as my heirs and sons as surely], as Reuben and Simeon are my sons.
