Genesis 48:17-21

And 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.

And Joseph said unto his father, Not so, my father: for this is the firstborn; put thy right hand upon his head.

And 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: but truly his younger brother shall be greater than he, and his seed shall become a multitude of nations.

And he blessed them that day, saying, In thee shall Israel bless, saying, God make thee as Ephraim and as Manasseh: and he set Ephraim before Manasseh.

And Israel said unto Joseph, Behold, I die: but God shall be with you, and bring you again unto the land of your fathers.
