Genesis 48:13-20

And Joseph took his sons and had them stand facing their grandfather Israel, Ephraim at Israel’s left hand, and Manasseh at Israel’s right hand. But Israel crossed his arms, and stretched out his right hand on the head of the younger son, Ephraim, and his left hand on the head of the firstborn son, Manasseh. He spoke this blessing over them: “May the God of my fathers, Abraham and Isaac, who lived devoted to him, the God who has been my Shepherd from my birth until this day, the Angel who has delivered me from all harm, may he bless these boys! May their lives echo my name, and the names of my fathers Abraham and Isaac. May they multiply into teeming multitudes throughout the earth!” When Joseph saw his father place his right hand on Ephraim’s head, he was not happy, so he tried to move his father’s hand from Ephraim to Manasseh’s head. “Not that way,” Joseph said to his father, “Here, father, put your right hand on the firstborn’s head.” But his father refused and said, “I know, my son, I know. Manasseh’s descendants will also multiply and become a great people. His younger brother will become even greater than he, and his tribe will one day give rise to many nations.” So Jacob blessed them that day, saying, “Israel will use your names when they pronounce blessings! They will say, ‘May God make you like Ephraim and like Manasseh!’ ”
