Genesis 48:13-22

Then he positioned the boys in front of Jacob. With his right hand he directed Ephraim toward Jacob’s left hand, and with his left hand he put Manasseh at Jacob’s right hand. But 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. Then 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, the 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.” But 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. “No, my father,” he said. “This one is the firstborn. Put your right hand on his head.” But 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.” So 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. Then Jacob said to Joseph, “Look, I am about to die, but God will be with you and will take you back to Canaan, the land of your ancestors. And beyond what I have given your brothers, I am giving you an extra portion of the land that I took from the Amorites with my sword and bow.”
