Genesis 48:1-6

Now it came to pass after these things that Joseph was told, “Indeed your father is sick”; and he took with him his two sons, Manasseh and Ephraim. And Jacob was told, “Look, your son Joseph is coming to you”; and Israel strengthened himself and sat up on the bed. Then Jacob said to Joseph: “God Almighty appeared to me at Luz in the land of Canaan and blessed me, and said to me, ‘Behold, I will make you fruitful and multiply you, and I will make of you a multitude of people, and give this land to your descendants after you as an everlasting possession.’ And 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; as Reuben and Simeon, they shall be mine. Your offspring whom you beget after them shall be yours; they will be called by the name of their brothers in their inheritance.
