Genesis 48:14-20

14But Israel stretched out his right hand and placed it upon Ephraim’s head (though he was the younger), and his left hand upon Manasseh’s head, crossing his hands (though Manasseh was the firstborn).

15Then he blessed Joseph and said, “The God before whom my fathers Abraham and Isaac walked, The God who has shepherded me throughout my life to this day,

16The Angel who redeemed me from all evil, May He bless the boys, and may they be called by my name, and by the name of my fathers, Abraham and Isaac. May they multiply to a multitude in the midst of the land.”

17When Joseph saw that his father placed his right hand upon Ephraim’s head, it was wrong in his eyes. So his took hold of his father’s hand to remove it from Ephraim’s head to Manasseh’s head.

18Joseph said to his father, “Not like that, my father, because this one’s the firstborn. Put your right hand upon his head.”

19But his father refused and said, “I know, my son, I know. He also will become a people, and he also will become great. But his younger brother will become greater than he and his seed will be the fullness of the nations.”

20Then he blessed them that day saying, “In you shall Israel bless by saying: ‘May God make you like Ephraim and like Manasseh.’” Thus he put Ephraim before Manasseh.
