Genesis 48:18-22

“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.”
