Genesis 48:17-20

17And when Joseph saw that his father laid his right hand upon the head of Ephraim, it displeased him: and he held up his father’s hand, to remove it from Ephraim’s head unto Manasseh’s head. 18And Joseph said unto his father, Not so, my father; for this is the first-born; put thy right hand upon his head. 19And his father refused, and said, I know it, my son, I know it; he also shall become a people, and he also shall be great: howbeit his younger brother shall be greater than he, and his seed shall become a multitude of nations. 20And he blessed them that day, saying, In thee will Israel bless, saying, God make thee as Ephraim and as Manasseh: and he set Ephraim before Manasseh.
