Genesis 48:1-5

Some time later Joseph was told, “Your father is ill.” So he took his two sons Manasseh and Ephraim along with him. When Jacob was told, “Your son Joseph has come to you,” Israel rallied his strength and sat up on the bed. Jacob said to Joseph, “God Almighty appeared to me at Luz in the land of Canaan, and there he blessed me and said to me, ‘I am going to make you fruitful and increase your numbers. I will make you a community of peoples, and I will give this land as an everlasting possession to your descendants after you.’ “Now then, your two sons born to you in Egypt before I came to you here will be reckoned as mine; Ephraim and Manasseh will be mine, just as Reuben and Simeon are mine.
