Genesis 48:3-6

3Jacob said to Joseph, “God Almighty appeared to me at Luz in Canaan and blessed me.

4He said to me, ‘I will make you fertile and increase the number of your descendants so that you will become a community of people. I will give this land to your descendants as a permanent possession.’

5“So your two sons, who were born in Egypt before I came here, are my sons. Ephraim and Manasseh will be mine just as Reuben and Simeon are.

6Any other children you have after them will be yours. They will inherit the land listed under their brothers’ names.
