Genesis 48:1, 5

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 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.
