Genesis 48:16

13 And Joseph took them both, Ephraim in his right hand towards Israel's left hand, and Manasseh in his left hand towards Israel's right hand, and brought [them] near to him.

14 And Israel stretched out his right hand, and laid [it] upon Ephraim's head, who [was] the younger, and his left hand upon Manasseh's head, guiding his hands by design; for Manasseh [was] the first-born.

15 And he blessed Joseph, and said, God, before whom my fathers Abraham and Isaac did walk, the God who hath fed me all my life long to this day,

16 The angel who hath redeemed me from all evil, bless the lads; and let my name be named on them, and the name of my fathers Abraham and Isaac: and let them grow into a multitude in the midst of the earth.

17 And when Joseph saw that his father laid his right hand upon the head of Ephraim, it displeased him: and he lifted his father's hand, to remove it from Ephraim's head to Manasseh's head.

18 And Joseph said to his father, Not so, my father; for this [is] the first-born; put thy right hand upon his head.

19 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.
