Genesis 48:15-18

And he blessed Joseph, and said, God, before whom my fathers Abraham and Isaac did walk, the God which fed me all my life long unto this day, The Angel which 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. {grow: Heb. as fishes do increase} 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. {displeased...: was evil in his eyes} And Joseph said unto his father, Not so, my father: for this {is} the firstborn; put thy right hand upon his head.
