Genesis 48:3-6

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

4He said to me, “I will give you many children, so that your descendants are many. In that way, you will become the ancestor of many nations. I will give this land to you so that it belongs to your descendants for ever.” ’

5Jacob continued to say to Joseph, ‘You have two sons that were born to you in Egypt before I came here. They will become my own sons. Ephraim and Manasseh will be my sons, just as Reuben and Simeon are my sons.

6Any children born to you after them will be your own children. They will receive part of the land that belongs to their brothers, Ephraim and Manasseh.
