Genesis 48:4-6

New Revised Standard Version, Anglicised

⁴ and said to me, “I am going to make you fruitful and increase your numbers; I will make of you a company of peoples, and will give this land to your offspring after you for a perpetual holding.” ⁵ Therefore your two sons, who were born to you in the land of Egypt before I came to you in Egypt, are now mine; Ephraim and Manasseh shall be mine, just as Reuben and Simeon are. ⁶ As for the offspring born to you after them, they shall be yours. They shall be recorded under the names of their brothers with regard to their inheritance.
