Genesis 48:14-20

14But Jacob crossed his arms as he reached out to lay his hands on the boys’ heads. He put his right hand on the head of Ephraim, though he was the younger boy, and his left hand on the head of Manasseh, though he was the firstborn.

15Then he blessed Joseph and said, “May the God before whom my grandfather Abraham and my father, Isaac, walked— the God who has been my shepherd all my life, to this very day,

16the Angel who has redeemed me from all harm— may he bless these boys. May they preserve my name and the names of Abraham and Isaac. And may their descendants multiply greatly throughout the earth.”

17But Joseph was upset when he saw that his father placed his right hand on Ephraim’s head. So Joseph lifted it to move it from Ephraim’s head to Manasseh’s head.

18“No, my father,” he said. “This one is the firstborn. Put your right hand on his head.”

19But his father refused. “I know, my son; I know,” he replied. “Manasseh will also become a great people, but his younger brother will become even greater. And his descendants will become a multitude of nations.”

20So Jacob blessed the boys that day with this blessing: “The people of Israel will use your names when they give a blessing. They will say, ‘May God make you as prosperous as Ephraim and Manasseh.’” In this way, Jacob put Ephraim ahead of Manasseh.
